This is the last question idk how do solve it : (

lilliana is training for a marathon. she runs the same distance every day for a week. on monday, wednesday, and friday, she runs 2 laps on a running trail and then runs 8 more miles. on tuesday and sunday, she runs 4 laps on the trail and then runs 4 more miles. on saturday, she just runs laps. how many laps does lilliana run on saturday?

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.
