Answer:
Explanation:
So we have direct proportions here.
So
715=11
845=x
845*11/715
x=13
To check our work.
715/11=65
65*13=845.
Basically, in this formula, you use cross multiplication. So A*B=B*A. B and B go together and A and A go together/
So we can use the formula x = b*b/a. Since A is one of the A's and the other value of A is missing, we can use this formula to find it.
Hope this helped, ask me if you have any questions.
