The last one I can help you with. Do you know how to do cross multiplication? I'll set it up for you: 375/100 = 1312.5/x Then, you would multiply 1312.5 by 100, and divide by 375. Hope I helped!

You're welcome. I'm glad I could help!

By what you said in the problem, I think you are trying to find a percent. In this case, you could set up an eqaution. Do you know cross multiplication. Well, just in case you don't, I'll show you. x/100 = 1.20/2.25 Then what you would do is multiply 1.20 by 100, then ...

Uggh... we learned this last year. I think I remember. I'm pretty sure that it means that -1 is the place where the line starts, and then you would use 1 to make the line. Since the number 1 is really the fraction 1/1 or 1 over 1, then to make the line on a chart you would...

Well, definitely not 5+3+4. I don't exactly get your other equations, so the one that makes the most sense to me is the first one, 5 * 3 * 4. What I would do is make a little chart. Number the shirts, and have the possible plant and shoes branching off, then count the ...

Let me try again: I know how you feel, being in a confused state. I'm almost always like that in algebra class. Don't trust me on this answer... I'm not positive if this is what you mean. Do you know about cross multiplication? If you don't, you do now. 1.24 ...

What I would do is replace the variables with the numbers and set it up like this: (-3 x 3) + (-2 x -1) -7. What's strange is that I got -14, too. The key could be incorrect, I have had mistakes in my math book before. If this homework isn't being graded, don't ...
