2x-6=90 would be the answer
R = radius of basketball
r = radius of tennis ball
R = 3.6r cube both sides
the ratio of the radii is 1: 3.6
cube both sides to find the ratio of the volumes
1 : 46.656 ( this many times greater)
Answer:
Part A:
C= cash Sue earns
H = hours Sue works
C is dependent upon H because C only changes when H is changed.
Part B:

(1,6)
Part C:
C=6H
First find the difference in prices...
475 - 275 = 200 so the price went down 200 dollars. No we need to find what percentage of 475 is 200.
475 × x = 200
x = 200/475
x = .4211
Now convert to percentage by multiplying by 100 (move decimal 2 places to the right)
.4211 = 42.11%
It is a 42.11% price reduction.
