Answer:
Equation: <u>3x + 5x = 40</u>
Earned Per Hour: <u>x = 5</u>
Step-by-step explanation:
Since it's an equation, there has to be an equal sign. The total is 40 and the variable is x. You babysit on Friday and Saturday. On Friday, 3 hrs, and on Saturday, 5 hrs. Your paycheck is x. So far the equation is:
<u>3x + 5x = 40</u>
This is saying that for 3 hours on Friday, you got x money per hour plus the 5 hours on Saturday. Which equals 40 dollars total. Now that we know the equation, we can solve.
First we have to combine like terms. So that's <u>3x</u> plus <u>5x</u> which is <u>8x</u>:
8x = 40
To find x, you divide 40 by 8 to get 5.
<u>x = 5</u>
Answer:

Step-by-step explanation:
Every 4 months, Eva reads 36 books.
You first need to find the number of books Eva can read in 1 month
By dividing the ratio by you find that Eva can read 9 books per month.
You then add 4 and 5 together to get 9 because Eva has already read for 4 months and is going to read another 5 months after joining the book club.
You use the monthly ratio and multiply it by for the grand total of 81 books for the nine months that Eva has read.
