this week claire hiked 8.5 kilometers less than twice the distance she hiked last week.
Write an expresion to represent the number of kilometers Claire hiked this week.
Let the distance she walked last week be "x".
distance this week = 2x-8.5
--------
If claire hiked 32.5 kilometers this week how far did she hike last week.
Solve: 32.5 = 2x-8.5
2x = 41
x = 20.5 km
----------------------------
If claire hiked 12.75 kilometers last week how far did she hike this week?
Solve 12.75 = 2x-8.5
2x = 21.25
x = 10.625 km
