PLEASE HELP I NEED IT!! Graham drove 42.3 miles in 15 hours. What is the unit rate for miles per hour?

2.82 miles per hour

Step-by-step explanation:

This is a fraction equal to

42.3 miles ÷ 15 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 15

42.3 miles÷ 15

15 hours÷ 15

=

2.82 miles

1 hour

=

2.82 miles

hour

= 2.82 miles per hour

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
