Scribe for Jan 22

Thursday, January 22, 2009
Today in class we talked about what we are going to do for the quiz tomorrow. For the quiz, Mr. Harbeck is going to take some of the questions we did on our homework on page 43. We also corrected our homework from page 43, and 44. Today, our home work is page 46, and 45 in our purple book. On 46 we only have to do 6 questions, and on 45 we have to do E to W. Below you are going to see some examples of the kind of questions that you might see on the quiz tomorrow.

-The slashes that you see in the questions are dividing symbols.

1. -4y+16=4
-4y+16-16=4-16
-4y=-12
-4y/-4= -12/-4
y= 3

Vefification
-4y+16=4
-4(3)+16=4
-12+16=4
4=4

2. 3n+8=20
3n+8-8=20-8
3n/3 =12/3
n=4

Verification
3n+8=20
3(4)+8=20
12+8=20
20=20

3. -x/3+4=20
-x/3+4-4=20-4
(-3)-x/3=16(-3)
x=-48

Verification
-x/3+4=20
(-1)(-48)/3+4=20
16+4=20
20=20

4.
-8t-23=41
-8t-23+23=41+23

-8t/-8=64/-8
t= -8

Verification
-8t-23=41
-8(-8)-23=41
64-23=41
41=41

    Hey Jai! Great scribe, but I think making a picture for some questions would be more helpful with the dividing questions, because the "/" sort of throws you off, but is still understandable. Anyway, good job!
