Can anyone tell me the formula I would use to solve this question.

If 2001.51 = 70% of X, what is X?

I know what X is, (2859.30) but if I didn't, and only had the 2001.51 number, what is the formula I would use to determine X?

And what area of math is this referred to as, (since I obviously need a course on it ;-) Thanks.

That's a 6th grade math problem.

Thank you for pointing that out, Abraham. What would we do without you?

Are any of you seriously mathematical? If so I have a question that should be simple, but none of my local geniuses can answer it.

Goody! How do you calculate the points at which the hour and minute hands of a clock are in the same exact position (or exactly opposite) other than 12:00?

Mind you, the exact times are of secondary interest at best. I mainly want to know how they'd be arrived at, simply because I'm an endlessly curious person (if a total mathematical failure).

I don't know how to calculate it.

The big hand passes the little hand once an hour, and is opposite it once an hour.

2 times an hour for whatever length of time you want. I don't know why you eliminate 12:00 - same thing.

If this is a trick question and you make me look like a retard, I'm going to knock you over the head with my mouse.

You're in good company in answering "everything else but" :)

Well, I don't know what you mean by that.

I have no clue either.

Is 120 times correct, is all I wanna know. :-)

Have fun here:

They discuss only when the hands are in a straight line/opposite each other.

22 times in a 24 hour period with discussion.

Edit: between 5 and 7 O'clock they're only in a straight line at 6. I see that now...with help.
