Let x = Craig's time
Let y = Tom's time
Create a system of equations to solve this problem.
8 = x + y
y = 4x
Substitute 4x into the y variable in the first equation.
8 = x + 4x. Combine like terms
8 = 5x. Divide each side by 5.
1.6 = x
Craig takes 1.6 hours to clean the house
0.75 per cubic foot of earth move.
Ignore all the words, you multiply 220 by 0.75 twice in order to find out what he is paid.
220 * 0.75 = $165
You are multiplying by 220 again because h<span>e moves the same amount to fill the trench.
220 * 0.75 = $165
$165 + $165
=
Your Answer:
$330

Answer:
You can solve this problem by doubling each original measure then putting them in the equation. So, a length of 6in becomes 12in, a width of 10in becomes 20in, a height of 9in becomes 18in. The equation is now 12x20x18. 12x20= 240. 240x18= 4,320. This means the new aquarium has a volume of 4,320in3.
