Answer:

Step-by-step explanation:

a. 1/2x = 10  x = 20

b. 1/4s = 8    s = 32

c. 1/3t = 6     t = 18

d. 1/5 y = 20    y = 100

4. Division

a. 4x = 32    x = 8

b. 13x = 39     x = 3

c. 5x = 25    x = 5

d. 10x = 100    x = 10

5. Mixed Practice

a. x + 4 = 7     x = 3

b. 33 - y = 44       y = -11

c. s + 18 = 26      s = 8

d. m - 40 = 20     m = 60

e. z + 100 = 100    z = 0

f. x + 22 = 23      x = 1

g. s - 4 = 96     s = 100

h. 1/4x = 4       x = 16

i. 24x = 3 x = 1/8

j. 1/5x = 50 x = 250

k. 1/3y = 33 x = 99

l. t + 12 = 16 t = 4

m. t - 12 = 16 t = 28

n. 1/2q = 8 q = 16

o. 12t = 24       t = 2
