Question

The Teton Club has hiked 18.5 miles

and has x miles left to go. The club
plans to hike 25 miles altogether.

Answer 1

25=18.5+x

x=6.5 miles

Explanation:

isolate the x by subtracting 18.5 on both sides.

25-18.5=18.5-18.5+x

you will end up with 6.5 because 25-18.5 is 6.5

therefore, x=6.5 miles
