Step-by-step explanation:

<u>Step 1: Define</u>

(4y - 3x - 2) - (7y + 4x + 3)

<u>Step 2: Simplify</u>

  1. Distribute negative:                                                                                       4y - 3x - 2 - 7y - 4x - 3
  2. Combine like terms (y):                                                                                 -3y - 3x - 2 - 4x - 3
  3. Combine like terms (x):                                                                                  -3y - 7x - 2 - 3
  4. Combine like terms (Z):                                                                                 -3y - 7x - 5

Water weighs 62.4 pounds per cubic foot. How much does the water in a tank that measures 7 ft × 4 ft × 9 in, weigh?
andriy [413]

Answer:

  • <u>1,310 lb</u>

Explanation:

<u>1) Calculate the volume of the water in the tank.</u>

  • Area of the base of the tank: B = 7 ft × 4 ft = 28 ft²
  • Height of the tank: H = 9 in = 9 in × 1 ft / 12 in = 0.75 ft
  • Volume of the tank: V = area of the base × height = B × H = 28 ft² × 0.75 ft = 21 ft³.

<u>2) Calculate the weight of 21 ft³ of water.</u>

Since this is not a chemistry question but a math question, I will not use the fomula of density but set a proportion with one unknown:

  • 62.4 lb / 1 ft³ = x / 21 ft³

Solve for x:

  • x = 21 ft³ × 64 lb / ft³ = 1,310.4 lb.

So, rounding to the next integer, the water in the tank weighs 1,310 pounds, when it is full.
