3(x + 2) + 4(x - 5) = 10
Use the distributive property:
3x + 6 + 4x - 20 = 10
Combine like terms:
7x -14 = 10
Add 14 to both sides:
7x = 24
Divide both sides by 7:
x = 24/7
1. Multiply the length, width, and height to get the volume of the box, which is 24 ft³. 2. Each cube has a volume of 4, right? So divide 24 by 4 to get 6. 6 boxes can fit into the crate.
Step-by-step explanation:
-1 / 2 + x = -21 /4
x = -21/4 + 1/2
x = (-21 + 2)/4
x = -19/4
