Question

15 points for both I need to turn it in tmr

Answer 1

7) A

8) C

Explanation:

7:

`(2)/(3)`x + 6 = 16 Substitute 15 for x

`(2)/(3)` x
`(15)/(1)` + 6 = 16

`(30)/(3)` + 6 = 16

10+ 6 = 16

16 = 16 Checks

8)

3r - 2r - 8 = -8r + 10 Combine like terms

r - 8 = -8r + 10 Subtract r from both sides

r - r - 8 = -8r -r + 10

-8 = -9r + 10 Subtract 10 from both sides

-8 - 10 = -9r + 10 - 10

-18 = -9r Divide both sides by -9

2 = r
