One cylinder has a volume that is 8 Centimeters cubed less than StartFraction 7 over 8 EndFraction of the volume of a second cylinder. If the first cylinder’s volume is 216 Centimeters cubed, what is the correct equation and value of x, the volume of the second cylinder?
StartFraction 7 over 8 EndFraction x + 8 = 216; x = 182 centimeters cubed
StartFraction 7 over 8 EndFraction x minus 8 = 216; x = 196 centimeters cubed
StartFraction 7 over 8 EndFraction x + 8 = 216; x = 238 centimeters cubed
StartFraction 7 over 8 EndFraction x minus 8 = 216; x = 256 centimeters cubed
The correct equation is StartFraction 7 over 8 EndFraction x + 8 = 216.
Solving for x:
StartFraction 7 over 8 EndFraction x = 216 - 8
StartFraction 7 over 8 EndFraction x = 208
x = 208 * StartFraction 8 over 7 EndFraction
x = 8 * 8 = 64 * 2 = 128
x = 128 centimeters cubed
Therefore, the volume of the second cylinder is 128 centimeters cubed.
