Answer:
1. c 2. a 3. b
Step-by-step explanation:
1. -9p - 17 = 10
-9p = 10 + 17
-9p = 27
p = -3
2. w/4 - 4 = 3
w/4 = 3 + 4
w/4 = 7
w = 7 · 4
w = 28
3. x/5 + 6 = 10
x/5 = 10 - 6
x/5 = 4
x = 4 · 5
x = 20
4. -2(m - 30) = -6m
-2m + 60 = -6m
-2m + 6m = -60
4m = -60
m = -15
5. 3.75 + 3.7 = 1.7 + 1.75x
1.75x = 3.75 + 3.7 - 1.7
1.75x = 5.75
x = 23/7
6. -6 - 7(c + 10)
= -6 -7c - 70
= -76 - 7c
7. 2x + 3(x - 2) - 2(x - 6)
= 2x + 3x - 6 - 2x + 12
= 3x + 6
8. c + 6 -3
= c + 3
10. -5p > -30
p < 6
13. 29 - 5x = 4; $5.00
14. 64 + w = 2w + 8; 56 pounds
