7x-2=5x+14<br> X=?<br> (step by step needed)
prisoha [69]

Answer:

x = 8

Step-by-step explanation:

Step 1: Subtract 5x from both sides.

  • 7x-2-5x=5x+14-5x
  • 2x-2=14  

Step 2: Add 2 to both sides.

  • 2x-2+2=14+2
  • 2x=16

Step 3: Divide both sides by 2.

  • 2x/2=16/2
  • x=8

Step 4: Check if solution is correct.

  • 7(8)-2=5(8)+14
  • 56-2=40+14
  • 54=54

Therefore, x = 8.

First find the area of the base, and multiply that by the height. That's the answer.

Area of the base: pi * 3*3 = 3.14*9 = 28.26
Volume of the cylinder: 28.26*8 = 226.08 cubic units
