last month maria hiked a 5 mile trail several times and a 10 mile 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 what would the equation look like ?

5x + 10y = 90

Step-by-step explanation:

X is the number of times she takes the 5 mile, so the total distance would be 5x. Y is the number of times she takes the 10 mile, so the total distance would be 10y. And together they equal 90 miles, so 5x + 10y =90. Hope this helps.

x=30
