Answer:
12308.8 cm^3
Step-by-step explanation:
First we need to fill in the variables for the formula
Now solve. Keep in mind the order of operations. I have rewritten the equation with parenthesis to make it easier
After solving, you should get 12308.8. Since these measurements were in centimeters, we need to add <em>cm</em> to the end. Also since this is in 3D we need to add ^3

Answer:

Step-by-step explanation:
Given the 2 equations
x + y = 1 → (1)
ax - by = c → (2)
In (1) subtract y from both sides
x = 1 - y → (3)
Substitute x = 1 - y into (2)
a(1 - y) - by = c ← distribute left side
a - ay - by = c ( subtract a from both sides )
- ay - by = c - a ( multiply through by - 1 )
ay + by = a - c ← factor out y from each term on the left side
y(a + b) = a - c ← divide both sides by (a + b)
y = ← substitute into (3)
x = 1 - =
