Explain how to use the distributive property to find 20x12?
The distributive property is not used for simplified multiplication. See http://www.algebrahelp.com/lessons/simplifying/distribution for information about how to use the distributive property to simplify other equations. 20 x 12 is already simplified, so the proper way to solve it is 12 x20 ----- 240 You could potentially factor and use the commutative property to find a simpler equation, ex. 20x12 -- break 20 into 10 and 2 10x2x12 -- multiply 2 by 12 10x24 -- multiply by 10 240

In algebra you can use function to express the idea that salary depends on the number of hours of training?
Yes! You can express this as a function, like this: In my example I will say that the salary is $240.00 and this is based on a standard 30 hours of training. g(x)=30x +240 What we are basically saying is that whatever number we plug in for g(x) would determine how much they are paid. For example if we add 20 times the amount of hours of training we would get g(20)=30x + 240 Then plug in 20 for our x 30(20) +240 the new salary would be $840 :)
Eight is what percent of 64 use porportion?
8 is what percent of 64:= 8 / 64= 0.125Converting decimal to a percentage:0.125 * 100 = 12.5%
What percent of 4000 is 6?
Why don't you use a calculator? 4000 x0.06 = 240 PerCent is; of a century, which is 100. So 6 percent is: 6 parts of 100 or: 6 divided by 100
How much of a 6 percent solution and a 12 percent solution would use to make 240 milliliters of a 7 percent electrolyte?
Let x be the volume of the 6% solution and y be the volume of the 12% solution. We have the following system of equations: x + y = 240 (total volume) 0.06x + 0.12y = 0.07 * 240 (electrolyte amount) Solving this system, we find x = 160 mL of the 6% solution and y = 80 mL of the 12% solution to make 240 mL of a 7% electrolyte.
