Answer 1

The expression which shows Number of miles more Allison hiked than Adrian is
`5x-5`.

Explanation:

Number of miles Allison hiked =
`9x`

Number of miles that Adrian hiked =
`4x+5`

We need to find Number of miles more Allison hiked than Adrian.

To Find Number of miles more Allison hiked than Adrian we will Subtract Number of miles that Adrian hiked with Number of miles that Allison hiked.

Framing in equation form we get;

Number of miles more Allison hiked than Adrian = Number of miles that Adrian hiked - Number of miles that Allison hiked

Number of miles more Allison hiked than Adrian =
`9x-(4x+5) = 9x-4x-5 =5x-5`

Hence, The expression which shows Number of miles more Allison hiked than Adrian is
`5x-5`.
