5/1, 15/3, and 10/2 are all valid answers to that question.
Surface area I think is the circle. So the formula to find the area of the circle is to do Pi times radius squared. Pi= 3.14 Radius in this case will be 2.2. (Radius is how much it measures out from the middle.) then you want to do 2.2 x 2.2 (since it's square) So the answer would be equal to (I think) 15.1976
Hey there! :D
Let's keep the fraction 5/7 in mind. We should be able to reduce everything to 5/7.
15:21 (divide both by 3) you get 5:7. That is equivalent.
10 to 14. Divide both by 2. 5 to 7. That is equivalent.
The correct answer is 28/20. That is not equivalent.
I hope this helps!

If you are trying to distribute, then simply multiply the 3x across to get (your answer):
Therefore, your answer would be -15x. Hope I could help!
Hello!
Judging by the question you have provided I have come up with an equation to find the answer!
The equation is as follows: $0.25(Amount of quarters)(40) + $0.10 (Amount of dimes)(50) + $0.05 (Amount of nickels)(40) = Total Money!
First you want to input the amount of each coin(s) that you have.
Your new equation should be
$0.25 (4)(40) + $0.10 (3)(50) + $0.05 (6)(40).
If you solve the equation you should get $67.00 as your total!
Hope this helped!
