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? x + y = 90 5x−10y = 90 90−10y = 5x 90 + 10y = 5x

Answer

Explanation:

Step1: Calculate total miles from mountain trail

The mountain trail is 5 - mile long and Maria hiked it (x) times. So the total miles from the mountain trail is (5x).

Step2: Calculate total miles from canal trail

The canal trail is 10 - mile long and Maria hiked it (y) times. So the total miles from the canal trail is (10y).

Step3: Set up the equation for total miles

The sum of miles from both trails is 90. So (5x + 10y=90). Rearranging this equation gives (90 - 10y = 5x).

Answer:

(90 - 10y = 5x) (the third option)
