Last month Maria hiked a total of 90 miles on two trails: a 5-mile mountain trail and a 10-mile canal trail. Let x
represent the number of times Maria hiked the mountain trail, and let y represent the number of times Maria hiked
the canal trail.
Which equation can be used to find
the number of times Maria hiked each trail?
O x + y = 90
O 5x - 10y = 90
90 - 10y = 5x
90 + 10y = 5x
