So in order to solve this we are going to cross multiply:
a 4
--- = --
15 5 so what were are going to do is we will take a and multiply it with 5 and we will take 15 and multiply it with 4. Now this gives us 5a and 60 so our new equation is:
5a = 60 now we are going to get our variable alone by dividing it by 5 and what we do on one side of the equation we do on the other:
5a = 60
÷5 ÷5 this gives us a=12
hope this answer helps

Divide 7 by 8 to get .875 and multiply that by 20 to get your answer.
Answer:
A) 
Step-by-step explanation:
The graph has x-intercepts at 
and 
, so our factors for the polynomial will be 
and 
. This means we can rule out options B and D.
Our graph also has a y-intercept of 
when 
, so if we let 
and , we can find the multiplier:
Thus, the correct equation is A)
