Question

Jared and maila will usually both run 3 miles each time they go running .This month,jared ran an additional 21 miles. Which answer choice shows an expression that represent the total distance jared and malia ran this month if j=the number of time that jared ran and m=the number of times that malia ran?

Answer 1

Total = m + j

= 3 + m + 21

Explanation:

Mails = 3 miles

Jared = 3 miles + 21 miles

j = m + 21

m = 3

Total = m + j

= 3 + m + 21

Where,

m = 3

Total = 3 + m + 21

= 3 + 3 + 21

= 27
