Next Scriber

Little Guy (Jerome)




Français/French Deutsch/German Italiano/Italian Português/Portuguese Español/Spanish 日本語/Japanese 한국어/Korean 中文(简体)/Chinese Simplified Tagalog/Filipino

Scribe Thing

We did the 2nd part of Transposing today.

Ya so uh. We used the distributave property to find the answer to the questions. i.e. 4(x+5)=3(x+12)

To get the answer you multiply he 5 in the first brackets by 4(the first number) and multiply 12 by 3(the first number after the equals sign) It should look like 4x+20=3x+36

Now all you do is balance. 4x+20=3x+36
-3x-20 -3x-2

Next
4-3=1 so 4x-3x=1x

1x divded by 1

Next


36-20=16 16 divided by 1 =16



Therefor X=16



Now The actual notes

*There are variables on both sides of the = sign
*Use transposing
*Simplify with the distributing property first
-Solve 1step after cancelling the right variable and left integer


DON'T FORGET TODAY'S HOMEWORK Pg. 41 on that penguin booklet!!

me da scribbler(EDITED!!!)

Well, 2day we made another hanburger hotdog thing, i forgot what its called...anyways it was on collecting like terms and transposing!
on collectiong like terms box1 #2 row, it was this....
10x + 75 - 5x = 110
10x - 5x + 75 = 110
+ 5x + 75 = 110

5x + 75 = 110 - 75
-- - 75 ---------
5 5
On row #3 it was...
-Circle the first term
-look for any like terms
*Rewrite the question with regrouped terms
-simplify so that you have 1 variable group and 1 integer group
-solve 2 step equation

on row 4 it was...
32-3x+10-2x+3=100
32+10+3-3x-2x=100
45 -5x=100-45
---- --------
-45 -5 -5

now row 5 it was....
-circle the first term
-find like terms
-solve 2 step
*remember integer rules

NOW THE TRANSPOSING SIDE!

6x+5=2x+13
-2x -2x

4x=8
-- --
4 4

x=2
6x-3=4x+9
-4x+3 -4x+3

2x=12
-- --
2 2
x=6

on row 4 it was....
4(x+5)=3(x+12)
multiply the 4 wit the x and multiply 4 with 5
multiply x wit x and 3 wit 12
4x+20=3x+36
-3x -20 -3x -20
take 3x away from 4x to make 1x and divide that by 1 then take 20 away from 36 and divide it by 1
x=16
------------------------------------------------------------------------------------------------
3(x+7)+2(x-5)=36
3x+21+2x-10=36

5x+11=36
-- -11 -11=25
5 divide 25 by 5
x=25 divided by 5
x=5

now on the last row #5
*there are variables on both sides of the = sign
*use transposing
*simplify with the distributive property 1st
-solve 1 step after cancelling the right variable and left integer!
and im done now hurray!


next scribbler is: GREY

ann's scribble

In math class we made those folded up pieces of paper booklets.

To make them you have to hamburger fold the paper twice then fold it into thirds. When you open it up there should be 12 squares. Then fold the bottom row of 4 up and the top row of 4 down so u should have a 'mouth' that opens up.

On the cover write each of these in a seperate box:

1 step equation using + or -

1 step equation using x or ÷

2 step equations

Distributive Property

Now on the inside of the top 'lip' write of each of these questions in each topic and solve:

1 step equations using + or -
x+6=10; x-7=30

1 step equations using x or ÷
x÷10=30; 3x=24

2 step equations
2x+5=15; x÷3+10=40

distributive property
3(x=3)

On the topside of the bottom 'lip' write the word explanation to each topic:

1 step equation using + or -
1.Isolate the variable
2.cancel using an oppistite
3.balance
4.substitue to check

1 step equation using x or ÷
1.isolate the variable
2.cancel using an oppistie
3.balance
4.substitute to check

2 step equations
1.isolate the variable
2.cancel the interger first
3.balance
4.isolate the variable
5.cancel the multiplier or divisor second
6.balance
7.substitute to check answer

Distributive Property
1. 2 terms inside the brackets
2.multiply the first and second term by the multiplier
3.get rid of the brackets in the expression

Now open up the bottom lip and in the middle row you write each of these questions that have a negitive sign in them and i'll solve it for u ppl.

1 step equations using + or -
-x+6=10 -6
-6
-x= 4
/-1 /-1

x=-4

-x-3=12+3
+3

-x= 15
x= -15


1 step equations using x or ÷
-3x=12/-3
/-3

x=-4


x/-4=7(-4)
(-4)

x= -28

2 step equations

-4x+3=-17 +3/-4
/-4 +3

x= -20/-4= 5

distributive property

-3(x+6)

-3(-x-6)

Now write this stuff under the right topics on the bottom inside 'lip'

1 step equations using + or -

-x=4 is not done
-x means (-1)(x) or -1 times x
divide both sides by -1

1 step equations using x or ÷

whatever u multiply or divide by use the same interger to get a positive variable
-3x/-3 NOT -3x/3

2 step equations

cancel interger
balance
cancel what is attached to the variable
dont forget the interger rules

distributive property

1 negitive sign (odd #) negitive answer
2 negitive signs (even #) postive answer

And thats it really. sry if u wanted sumthing visual mr harbeck but im to lazy to do something like that.
The next scribe is ... Sachelle

Scribe>>.KAhlah

Today in math class we corrected pg 40 in one of our booklets. We also took down some note, the following:

The Distributive Property

3(x+6)- two terms inside the brackets
Multiplied by 3

This means 3 groups of (x+6):
(x+6)
(X+6)
(X+6)

You can solve the distributive property this way:
3(x+6) 3(x)+3(6)
3x+18

e.g.1) 5(2x+3) e.g.2) 3(4x+7)
10x+15 12x+21

e.g.3)-6( x+7)
-6x+-42 - remember integer rules!!!

e.g.4) 3(-2x-2)
-6x-6
This is what we learned today!!:)

.Teara's Scribble

Okay well, today in math class we had a small quiz.
After that we put in some sheets in our math binder thingy
Then we attempted to work on TLE 8 but it didn't work out so we worked on that 6.8 math sheet in class for 15 minutes, we had to do questions 1-20 and that's all
for the next scribe i choose Junnel
PS: in our binder we put in the blue books, the integer quiz, and some other stuff.
on 6.8 sheet one of the questions was:
x-9=13 you are supposed to add the 9 to both sides
+9 +9
x=22

Manila Scribe

One step equation solving using multiplication and divison.
1. isolate
2. cancel using the opposite
3. balance
4. substitute
* When cancelling using multiplication or division you still have 1x
E.G.1
3x=24
--- ---
3 3
x=8

When dividing you want to show a number kissing a bracket
E.G.2
x
-- =15
3
^cancel by using opposite
(3)x
----- = 15(3)
3 x=45

February 9 2006 scribe-Kimberley Besyk

make a sentense with the words expression, equation, algebra, 3x+6=14 and 2x-5.
An algebraic expression like 2x-5 is a pattern. There are many answers

An algebraic expression has only ONE (1) answer.

One step problem solving

x+6=9-6
-6
x=3
3+6=9

1)isolate the variable
2)cancel out using an opposite
3)balance
4)substitute to check answer

x+8=20-8
-8x=12
12+8=20

Hint--> when canceling integers you need a result of 0.

-13+y=40+13
+13
y=53
53+13=40

This is different *13-x=12* .

Dilly's Scribbles via Harbeck

Well mabck in the day, we learned how to solve equations. First Mr. P taught us how to do one step equations with adding, subtracting multiplying and dividing.

Adding 4 + x = 20
4 + x -4 = 20 -4
x = 16


Subtracting x - 5 = 2
x - 5 +5 = 2 +5
x = 7

Multiplying 3x = 24
3x/3 = 24/3
x = 8

Division x/7 = 6
(7)x/7 = (7)6
x = 42
He also told us that when you do 2 or more step equations we isolate the variable and use coefficient first ( aka reverse order of operations)

7x + 9 = 30
7x + 9 -9 = 30 -9
7x = 21
7x/7 = 21
/7

x=3

Lost Algebra

I created a post on the weekend all about the algebra you are doing. I am reposting it for your amusement. Please complete as much of this as you can and leave a comment behind about how you did.

Remember me Grade 8’s. Since I have been gone …only two days you must be missing me. Even if you are not missing me here are some excellent links to reinforce your learning.

The foundation to understanding algebra is to know integers. Here are two links that will reinforce what you need to know.

Try this Integer Quiz. If this is not familiar to you remember your order of operations and try again.

From this link you can see a movie on adding and subtracting integers. It is well done. If this link does not bring up the movie immediately click on the adding and subtracting integer link on the page.


Your first algebra lessons are dealing with words like term, variable, expression and equations.


Here are some helpful resources for you.
Extra help words to expressions
Extra help on variables and expressions

Here are three quizzes to see how well you did.

Substitution algebra
Solving Equations using Addition or Subtraction
Solving Equations using Division or Multiplication

Remember Leave comments to tell me how you did.

Scribes???

Being a class scribe is a serious responsibility. You need to recapture the class for that day and post it for all to see.

As Richard has said in his posts

” The purpose of a scribe is to inform the reader what your doing and by doing so you relearn what you learned that day making you just a bit more smarter. Also if the reader reads the scribe then they also relearn. To think about it. Scribing is all about learning and learning… etc.”

Try to scribe or comment daily.

im picking up where we left off

Hi im scribber! yay! ok... what did we do yesterday....

well we had mr Pointon continue to teach us algebra.
and we did that writting the algebricc expressions to english and visa-versa.
I think we also did some tle8 on the computers on the patern relation algebraic translating stuff thing.
Well for all of us that were with mr.P. last year its a review. For those who werent...
3x-8+6=10
this would be read:three multiplied by a quantity decreased by 8 and increased by six is equal to ten
i cant remeber but i think we might have gotten some note stuff too...
coefficient-the number before a variable
variable-a symboly representing an unknown value
constant-a number without a variable
i think there might be more but i cant remember
it was semi medium easy difficult to understand sort of...
the homework was that sheet that mr.P. called the "long paper"
p.s. remember its two sided!
ok i think thats it...
if ive forgotten anything or you have any questions please leave a comment...
ok i declare the next scribe to be....dilley
Thanks all, bye!

Look I'm Back

Sorry I haven’t been commenting or visiting lately. I’ve been crazy studying for exams… But now that Second Semester has started at Daniel Mac. I’m back. Hahaha. Now that I have seen that you guys are scribing. There are some excellent scribes going on and I assure you they will get better. You just have to push around each other on the blog. That’s the evolution of a blogger right there. You guys have to compete with each other to see who’s the best blogger out there. Hahahaha.

There are plenty of Examples of scribing.

Super (Secret) Scribe

Scribe or What

Scribe

Scribe Scribles

Yeah there all from the PC30S blog. Hahaha. Well you see. The purpose of a scribe is to inform the reader what your doing and by doing so you relearn what you learned that day making you just a bit more smarter. Also if the reader reads the scribe then they also relearn. To think about it. Scribing is all about learning and learning… etc.

So keep those scribes coming. And here’s a tip. Like in the examples that I posted. Try to use photos to make your scribe look even more better. Hahaha

Help the scribe

Some advise to bloggers. You need to be prepared to put a post up to the blog. People are counting on you to keep the scribe alive. If you are having difficulty post a blog and then go back in and edit the scribe.

To the scribes fellow classmates, If the scribe needs to have information added to it, post comments and add information you think will be helpful.

You all are doing a great job. I miss being at school. This is my link to you right now. Keep me informed and I will add comments if I can.

Keep scribbling.
