For x = ay - bz:

Add bz to both sides:

ay = x + bz

Divide a on both sides:

y = (x + bz)/a

For xy + yz = 10:

Distribute y from the left side:

y * (x + z) = 10

Divide by x + z:

y = 10/(x + z)

For (ab - ac)/z = x:

Multiply by z on both sides:

ab - ac = xz

Take out a from the left side:

a * (b - c) = xz

Divide by b - c on both sides:

a = xz/(b - c)

olchik [2.2K]

Answer:

V = \frac{4}{3} \pi R^{3} and

v = \frac{4}{3} \pi r^{3}

Step-by-step explanation:

Dawn wants to compare the volume of a basketball with the  volume of a tennis ball.

Now, if the radius of the basketball is R and that of the tennis ball is r, then the formula that can be used to determine the volume of each ball will be

V = \frac{4}{3} \pi R^{3} and

v = \frac{4}{3} \pi r^{3}

Now, dividing V by v we can compare the volume of the basketball and the tennis ball. (Answer)
