1. Find the value of y in this equation 16y=164
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.
