If you use one pound of one aluminum alloy and one pound of another aluminum alloy to make a third aluminum alloy, you would get two pounds of the third aluminum alloy.

Answer: 2 pounds of third aluminum alloy

If  the  expression 0.24 x + .49 is an equation of the form 0.24x + 0.49 = 0, then x = -0.49/ 0.24 = 2.04

Answer: x= 2.04
