a. 10 1/4

b. 180

c. 16 1/4

d. 32

2. Find the value of Z in the following equation 8Z=64

a. 8

b. 512

c. 72

d. 56

3. given the formula D=ABC, WHAT IS THE FORMULA FOR C

a. c=ab divided by d

b. c=ad divided by c

c. c= d divided by ab

d. c=abd

1). 16 Y= 164. ( then divided)

Y= 164 : 16

Y= 41 : 4

Y = 10 +1/4

2) 8z = 64. (then divided)

z= 64 :8

z= 8

3. D = A•B•C. ( divided)

D : A•B = C

C= D: AB

c. c= d divided by ab

**Solution:**

(1) we have been asked to find the value of y in this equation 16y=164.

The given equation can be solved as below

\( 16y=164.\\ \\ \text{Divide both the sides of 16 we get}\\ \\ y=10.25=10 \frac{1}{4} \\ \)

**Hence the correct option is a**

**2**. Find the value of Z in the following equation 8Z=64

we are given that

\( 8Z=64\\ \\ \text{Divide both the sides by 8 we get}\\ \\ z=8 \)

**Hence the correct option is a**

**3.**given the formula D=ABC, we have been asked to find the formula for C.

we can solve it as below

\( D=ABC\\ \\ \text{Divide both the sides by AB we get}\\ \\ \frac{D}{AB}=C\\ \\ C= \frac{D}{AB}\\ \)

**Hence the correct option is C. **
