Answer:
Sarah's age is 60 years
Step-by-step explanation:
The correct question is:
64 is 4 times the difference between Sarah's age, a, and 44. Assume Sarah is older than 44. Write an equation to determine Sarah's age
Let
a ----> Sarah's age
we know that
The difference of Sarah's age and 44, all multiplied by 4 is equal to 64
so
The linear equation that represent this problem is
[tex]4(a-44)=64[/tex]
Solve for a
Apply distributive property left side
[tex]4a-176=64[/tex]
Adds 176 both sides
[tex]4a=64+176\\4a=240[/tex]
Divide by 4 both sides
[tex]a=60[/tex]
therefore
Sarah's age is 60 years
