7 1/2 pints into quarts is 3.75
Let's give Cindy's age a variable.
Cindy's age = x
Cindy multiplies her age by 5
x(5)
Subtracted by 12
x(5) - 12
Divide by 3
(5x - 12)/3
The result was 16
(5x - 12)/3 = 16
Let's solve
Multiply both sides by 3
(5x - 12) = 48
Open brackets
5x - 12 = 48
Add 12 to both sides
5x = 60
Divide by 5 on both sides to isolate x
x = 12
Cindy is 12 years old.
Answer:
x = 63
Step-by-step explanation:
<u>Step 1: Solve for x by multiplying both sides by 9</u>
x/9 * 9 = 7 * 9
<em>x = 63</em>

Answer: x = 63
The answer is x= 46 because 180-134=46
