The expression 9x represents the number of miles Allison hiked, and 4x + 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.

Question 7 options:

5x – 5

–5x + 5

5x + 5

13x + 5

Respuesta :

For this case we have that Allison traveled 9x miles, while Adrian traveled 4x + 5 miles. The variable "x" represents the number of days.

We want to know how many miles of Allison toured Adrian, for this we subtract:[tex]9x- (4x + 5) =[/tex]

We take into account that:[tex]- * + = -[/tex]

[tex]9x-4x-5 =\\5x-5[/tex]

ANswer:

[tex]5x-5[/tex]

Answer:

Expression to show how many more miles Allison hiked than Adrian is:

5x-5

Step-by-step explanation:

Number of miles Allison hiked = 9x

Number of miles that Adrian hiked = 4x+5

Miles Allison hiked more  than Adrian

= 9x-(4x+5)

=9x-4x-5

=5x-5

Hence, expression to show how many more miles Allison hiked than Adrian is:

5x-5
