That's funny... I know someone in my spanish class whose name is Cecilia... well anyway, I don't know the translation myself, but I would try going on a translation website or google "translation websites" Hope I helped!

Just wondering... how did you get the x to the other side? And how did you get rid of the 25mph? Thanks!

I'm having a little trouble with this problem... Please try and walk me through the problem, too: #1. A motorboat leaves a dock and travels at an average speed of 15 mi/h toward an island. The average speed on the return trip is 10 mi/h. How far is the island from the ...

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!

**algebra! help!**

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

**algebra! 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...

**math help**

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 ...

Well, I could help you more if I could see the table... but that's okay. I think you're right for answer a). Well, I think what they meant for majority rule is whoever got the most votes, which would be (ADBC). But I don't know what plurality rule is. Sorry! Hope I...

**Ignore my last response! It didn't work!**

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 ...

Here is my problem. Please walk me through how you got to the answer. Three-fourths of a number equals 3 times the number increased by 9. Is this the correct equation? 3/4n = 3n + 9 Here's another. In this one, does "is" mean "equals"? One-fourth of a ...

Well, I think a footnote is in a textbook when a number is after a word (that almost looks like an exponent in math), and at the bottom of the page, it has all the words with their numbers on that page. Next to each word/number pair it has a definition or explanation. Hope I ...

Thanks! Could you explain how you got your answer a little more and give me the numbers, too? Do you have any idea for the answer to number 2? Thanks so much!

Once again, I have some confusing problems for math. If you know any answers, even if you only know one, please tell me the answer and walk me through it so I can actually understand how you get to it. Thanks! #1: A space craft travels at a speed of 8/10 of a mile per second. ...

I think what you are supposed to do is divide the sentence in half, so it would make two sentences that make sense. I'm not positive, though. Hope I helped!

Here are two more problems I have for homework tonight. I have gotten answers, but I used "guess-and-check" and could not find an equation like I am supposed to. If you answer, please tell me if my answer is correct, walk me through your way of solving it, and if you...

Interesting-- some of your problems are similar to the ones that are stumping me! Maybe you would know some of mine. They are a few ones below yours, under Algebra by Celina. I'll try to help you. #1, I can't help you with. For #2 and #3, I would choose one of the ...

**Algebra**

That's the problem. You see, if it had said how many kids or how many girls there are, that would have helped. I copied the problem word for word, so that's all there is. Maybe my teacher messed up and forgot some info. Thanks for helping! :)

**Algebra**

Please help!!! I have a worksheet of problems to do for homework, most of which I don't understand. My teacher hasn't really been answering my questions well. We are supposed to write equations, but if you have another way, that is fine, too. If you know any of the ...

I remember learning this. I'll show you how to do number 1. Think, does tossing the dime affect the outcome of tossing the quarter. And for number 2, would taking out a card from the deck affect what card you would get next? If you need more help, respond again. Hope I ...

**rudcing fractions**

Try to think of factors that go into both of these numbers-- the one that I can think of is 9. Divide both of them by 9, or another factor, and that is your reduced fraction. Hope I helped!

**math urgent help needed**

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 ...

**Dog Breeds**

I agree with GuruBlue, chihuahuas are very hyper sometimes and yippy. The elderly man might not be able to handle it and the cats might become scared. I really don't know about the other dog breeds. Probably the English Toy Spaniel. Hope I helped!
