The volume of two spheres are in the ratio 27:125. The ratio of their areas is 9:25
Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 10 to both sides
-6 (+10) = n/2 - 10 (+10)
10 - 6 = n/2
4 = n/2
Next, isolate the n. Multiply 2 to both sides
4(2) = n/2(2)
n = 4(2)
n = 8
8 is your answer
hope this helps
