THIS IS THE LAST QUESTION IDK HOW DO SOLVE IT :(
harkovskaia [24]

Answer:

6 laps.

Step-by-step explanation:

On Monday she runs 2x + 8 miles, where x miles = the length of the trail.

On Tuesday she runs 4x + 4 miles and this is the same distance as Monday, so

2x + 8 = 4x + 4

4 = 2x

x = 2  miles which is the length of the trail.

So each day she runs 4(2) + 4 = 12 miles.

So on Saturday she runs  12/ 2 = 6 laps.
