Question

Eileen drove for 85 minutes. This is 21 more minutes than one third the number of minutes Ethan drove. How do I put this into an equation?

Answer 1

Answer:85= (3x) -21

Explanation:

Answer 2

So let's start out by labeling Ethan as X

Since 85 is 1/3 of what Ethan drove, that means Ethan drove 3 times of 85.

85= (3x) -21
85 -21 = 3x
60=3x
20 = x
