Hi there
To answer you question the answer is:
Carrie read at a rate of 27.5 pages per hour.
Answer:
n = 21
Step-by-step explanation:
Given
n + 19 = 40 ( subtract 19 from both sides )
n = 40 - 19 = 21
Answer:
$4/ hour
Step-by-step explanation:
every hour you go you add 4 dollars
example: 1 hour is $2
2 hours is $6
You’d set up a proportion. I did 25/15=7x-40/18.
Then you would cross multiply to get 15(7x-40)=450
Distribute the 15.
105x-600=450
Add 600 to both sides, so the -600 cancels out.
Then you’re left with 105x=1050
Divide both sides by 105 and you get x=10
