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

Answer 1

1. 16y = 164 <=> y = 164/16 <=> y = 10.25 or 10 + 1/4. So the answer is a. 2. 8Z = 64 <=> Z = 64/8 <=> Z = 8. So the answer is a. 3. D = ABC <=> C = D/AB. So the answer is c.

Answer 2

Answer:

1.

Option a is correct

2.

option a is correct

3.

option c is correct

Step-by-step explanation:

1.

Given the equation:

$16y =164$

Divide both sides by 16 we have;

$y= \frac{164}{16} = \frac{41}{4}=10\frac{1}{4}$

⇒$y = 10\frac{1}{4}$

2.

Given the equation:

8Z=64

Divide both sides by 8 to get Z;

$Z = 8$

3.

Given the formula:

$D = ABC$

Find C:

Divide both sides by AB we have;

$\frac{D}{AB} =C$

or

$C = \frac{D}{AB}$
