Sarah and joe have a combined age of 41. Sarah's age is 7 years less than 3 times joes age. How old is Sarah ?

Question

It's math 1, 9th grade

 

Answer 1

Hi Cheyenne, let j represent Joe's age. Then Sarah's age will be: 3j - 7. The total ages equals 41.

 

Equation:

 

j + (3j - 7) = 41

 

j + 3j - 7 = 41

 

Combine terms:

 

4j = 48

 

j = 12

 

Joe's age is 12.

 

Sarah's age is: 3 * 12 - 7, or 29.
