Answer:
9. 32 (1/20) = 1.6
25 (1.6 = 40
5x + 5 = 40
5x + 5 - 5 = 40 - 5
5x = 35
(1/5) 5x = 35 (1/5)
x = 7
10. 24 (1/6) = 4
4 (4) = 16
x + 6 = 16
x + 6 - 6 = 16 - 6
x = 10
11. 20 (3/4) = 15
12 (3/4) = 9
2x - 11 = 9
2x - 11 + 11 = 9 + 11
2x = 20
(1/2) 2x = 20 (1/2)
12. 8 (1/4) = 2
10 (1/2) = 5
-3 + x = 5
-3 + 3 + x = 5 + 3
x = 8
13. 10 (1/5) = 2
6 (2) = 12
2x - 10 = 12
2x - 10 + 10 = 12 + 10
2x = 22
(1/2) 2x = 22 (1/2)
x = 11
14. 16 (1/8) = 2
8 (1/2) = 4
2x - 16 = 4
2x - 16 + 16 = 4 + 16
