Hi, I'm happy to help!
First off, we need to arrange an equation for what is being asked. 15 is 20% of her earnings and we don't know her total earnings.
15=20%×__
We can write this percentage as
15=0.2×__
We then change the equation to do the inverse operation, which is division, this makes it easier to solve.
15÷0.2=__
Now, we solve
15÷0.2=75
<u>She earned $75</u>
<u></u>
I hope this was helpful, keep learning! :D
I believe the correct answer is B. Hopefully my answer is useful!
Please mark as brainliest as well, thanks!

Answer:
8, 15 and 17 feet respectively
Step-by-step explanation:
Let the shorter leg=l feet
The longer leg of a right triangle is 7 ft longer than the shorter leg, therefore Length of the longer leg=(l+7) feet
The hypotenuse is 9ft longer than the shorter leg. Therefore Length of the hypotenuse=(l+9) feet
Using Pythagoras Theorem
This results into:
l-8=0 or l+4=0
l=8 or -4
Since length cannot be negative, The length l=8 feet
The sides of the rectangle are therefore: 8, 15 and 17 feet respectively
Answer:
The second equation which is a(b+c) = ab + ac.
Step-by-step explanation:
Remember that when you think of the word distribute, you want to see a variable or a number behind the parentheses. The fourth equation would not work despite there being distributive in which it will give you abc. The second equation is a great example of what a distributive property problem may do.
