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

Step-by-step explanation:

Let us assume that

x represents the number of times she hiked the 5-mile trail,

y represents the number of times she hiked the 10-mile trail.

If Maria hiked 5-miles trail for x number of times, so distance hiked by her is 5x miles.

If Maria hiked 10-miles trail for y number of times, so distance hiked by her is 10y miles.

So the total distance hiked by her is the sum of both 5 mile and 10 mile trail, so total distance hiked by her is,

But this is given as 90 miles, so

i would have to say it is c.

this is answer of 144 cubic meters
