5x - 5
Step-by-step explanation:
Allison hiked more than Adrian:
Number of miles Allison hiked - Number of miles Adrian hiked
= 9x - (4x + 5)
= 5x - 5
EDITED VERSION AFTER RELISED I'M WRONG :D
Hope this help you :3
Allison: 9x
Adrian: 4x - 5
To find the difference, we subtract Adrian's number of miles, 4x + 5, from Allison's number of miles, 9x.
9x - (4x + 5) =
We think of the negative sign to the left of the parentheses as a -1, and we distribute it by multiplying -1 by 4x and multiplying -1 by 5.
= 9x -1(4x + 5)
= 9x - 4x - 5
Now we combine like terms. The only like terms are 9x and -4x.
r=40% or .4
