Scribepost for 02-20-09



So today we corrected our algebra questions.

These are the questions.

1. a+5=11
a+5-5=11-5
a=6

Verify
a+5=11
6+5=11
11=11


2. b-3=7
b-3+3=7+3
b=10

Verify
b-3=7
10-3=7
7=7

3. c/5=25
c/5x5=25x5
c=125

Verify
c/5=25
125/5=25
25=25

4. 6d=30
6d=30/6
d=5

Verify
6d=30
6(5)=30
30=30

5. 7e+8=29
7e+8-8=29-8
7e/7=21/7
e=3

Verify
7e+8=29
7(3)+8=29
21+8=29
29=29

6. 2f-2=8
2f-2+2=8+2
2f/2=10/2
f=5

Verify
2f-2=8
2(5)-2=8
10-2=8
8=8

7. g/3+2=7
g/3+2-2=7-2
g/3=5
g/3x3=5x3
g=15

Verify
g/3+2=7
15/3 +2=7
5+2=7
7=7

8. h/4 -3 =2
h/4+3+3=2+3
h/4=5
h/4x4=5x4
h=20

Verify
h/4-3=2
20/4-3=2
5-3=2
2=2

9. 4x+2+3x=9
7x+2=9
7x+2-2=9-2
7x/7=7/7
x=1

Verify
4x+2+3x=9
4(1)+2+3(1)=9
4+2+3=9
6+3=9
9=9


10. There are two more than twice as many dogs as cats in the vet.
If there are six cats, how many dogs are in the vet? Show all of your work including the equation and verifying and answer in sentence.

6 cats d=dogs
6x2+2=d
12=2=d
14=d


Verify
6x2+2=d
6x2+2=14
12+2=14
14 = 14

There are 14 dogs in the vet.

So this is what we did today.


I pick Kamille for the next scribepost.
