Last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x

represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail.

if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail?

o x + y = 90

5x – 10y = 90

o 90 – 10y = 5x

o 90 + 10y = 5x
