V ,= 4/3 πr³
solve for r
3V/4=r³
so r is the cubed root of 3V/4
An example of a ratio would be:
1:2
3:4
5:6
An example of a proportion would be:

Answer:
x=-1, y=-3. (-1, -3).
Step-by-step explanation:
x+y=-4
3x-6y=15
---------------
x=-4-y
3(-4-y)-6y=15
-12-3y-6y=15
-12-9y=15
9y=-12-15
9y=-27
y=-27/9
y=-3
x+(-3)=-4
x-3=-4
x=-4+3
x=-1
