Warning:

. You just wrote - and +, adding them both would result in a 0; (positive + negative = 0). If you haven't checked twice before asking, it is your problem. I'm going to solve for:

x(100-15x) when x = 5.

Answer:

Step By Step Explanation:

You'll need to substitute (that word is hard, it means replace though) the x, and get a proper equation (because they already gave you the x).

Look at how ugly and hard this is: x(100-15x) When x = 5.

Now it's better when replacing the x: 5(100-15×5)

Put it in a calculator if you wanted to avoid step by step work, but I'll show you how to do it step by step if you wanted.

5(100-15×5)

(5)×(100)+(5)(-75)

500-375

=125.

So, write this for your answer:

x(100-15x) = 125 Because 5(100-15×5)=125. And x = 5.
