Question

The expression 8x represents the number of miles Allison hiked, and 3x + 5 represents the number of miles that Adrian hiked in x days. Write an expression to show how many more miles Allison hiked than Adrian.

Answer 1

The solution expression is a subtract, because we need to find the difference between two values by subtract

then

`(8x)-(3x+5)`

and simplify

`\begin{gathered} 8x-3x-5 \\ (8-3)x-5 \\ 5x-5 \end{gathered}`

right expression is 5x-5
