Answer: x = -39
Step-by-step explanation:
85= -6x+7+4x combine like terms (-6x, 4x)
85= -2x+7 subtract 7 from both sides
78= -2x divide both sides by -2
x= -39
Answer:
254.5 Inches Cubed
Step-by-step explanation:
Formula for Finding the Volume of a Cylinder:
The radius is 3 inches.
The height is three times the radius.
Multiply the radius by three to get the height.
The height is 9 inches.
Use the formula to find the volume.
The exact volume is 81 inches cubed.
≈ 254.47
254.47 ≈ 254.5
The volume of the cylinder should be about 254.5 inches cubed.
negative = down or left positive = up or right
