3(x + 1) = 5(x - 2) + 7

  • Distribute 3 and 5 inside their respective parentheses.

3x + 3 = 5x - 10 + 7

  • Combine like terms.

3x + 3 = 5x - 3

  • Add 3 to both sides.

3x + 6 = 5x

  • Subtract 3x from both sides.

6 = 2x

  • Divide both sides by 2.
<h3>x = 3</h3>

The diameter of a volleyball is 8.15 inches. What is the volume of the ball, rounded to the nearest hundredth?
Nana76 [90]
<span>So we want to know the volume V of the volleyball if we know the diameter d=8.15 inches and we need to round it to the nearest hundreth. The volume of a volleyball is V=(4/3)r^3*pi, and since 2 radius are equal to the diameter we need to get the radius, so 2r=D and r=D/2 or r=4.075 inches. Now we get the volume after inputting the numbers: V=283.303032 inches^3. Rounded to the nearest hundreth: V=283.30</span>
