Question

10. w – 2 = –3 (1 point)
w = –3/2
w = –5
w = –1
w = 6
11. 2.8 = 2y (1 point)y = 1.4
y =1/2
y = 2.8
y = 0.6

Answer 1

12. –9 =r/4 (1 point
)r = 36
r = 13
r =9/4
r = –36

Answer 2

For 10.
Add 2 to both sides.

For 11.
Divide both sides by 2.

For 12.
Multiply both sides by 4.

Answer 3

14. Which equation is an identity? (1 point)11 – (2v + 3) = –2v – 8
5w + 8 – w = 6w – 2(w – 4)
7m – 2 = 8m + 4 – m
8y + 9 = 8y – 3
