Need help with a math problem, please!?

weell the two digits have to be either 6 and 2, or 4 and 3, since those are the only two single digit pairs that make 12. and 6 +2 = 8, so its either 26 or 62. given the domain, the answer is 62.

If it's math you can get some pretty good help at math.com. going to google for extra practice in pretty much anything. edhelper has worksheets you can print.

simply subtract 7 from both sides. This leave you with\n\nx<_3

Let x = "one number". \nThen, the "another number" is 2x.\n\nWhen the larger number is decreased by 10,\n\n2x - 10\n\nThe result is 2 greater than the smaller number\n\nx + 2\n\nTherefore,\n\n2x - 10 = x + 2, and\nx = 12.\n\nSo the two numbers are x and 2x, or 12 and 24.\n\nLet's put it back into the problem.\n\nOne number is twice another.  24 is twice 12.\nWhen the larger number is decreased by 10 (24 - 10 = 14), the result is 2 greater than the smaller number (2+12 = 14).  Therefore that's the answer!\n\nHappy solving!

If decimals are allowed, then (73+7)*.3 is a nice solution :)\n\nIf not, then the only solution I could find is (3+(3/7))*7\n\nEDIT : As for the initial question, absolutely! Math is my favorite subject, even in college. I won several contests in high-school, and love any sort of math puzzles. If you know of any more, please e-mail me :)\n\nSubmarinerdave : Heh. That's what I thought of as well, my sister has a 24 contest at her school two years ago :) A similar but more challenging game is the 2006 math game, where you try to make numbers from 1 to 100 using the digits 2,0,0, and 6.

I think this is also the 'trial and error method'\nYou will have an equation where you do not know the value of x.\nKeep on substituting different values of x into the equation until you come up with the right answer.\nIf you are lucky, you may have been told that x lies somewhere between 2 values.\nBest way to do it is to choose a number, get the answer, then choose another number a fair bit larger than the first. If the answer you want is between these 2 values, choose a number about half way between the 2 and so on.

Try starting with a proportion. Let K be the cost we are looking for.\n\nb / x = K / y\n\nNow solve for K.\n\nK = by / x

Use a calculator and raise it to the 1/3 power.\nDon't try to do it by hand...

Need to say what you are doing with the problem: solving for x, solving for y, other?\ny=(3/2)x+(7/4)

I posted these sources earlier to someone else who was looking for math help.\n\nGood Luck!!

Dude, so simple.\n\nYou need to find a # that is the lowest multiple of both 3 and 2.\n\nSo 1/2 + 1/3 changes to X/6 + X/6\n\nTo find out the top # you do the same thing that you did w/ the bottom #\n\n1 x 3   1 x 2     3     2      5\n----- + -----  = --- + ---  = ---\n2 x 3   3 x 2     6     6      6\n\nHay, if I help som 1 cheet, than I show them how to the problem, ok?\n\nJackmac :P~

that is a really simple question, so if you have a calculator you should be able to get it, otherwise, it is your homework and I refuse to give you an answer to your homework. I would actually HELP you to get the answer if you asked for HELP doing it.\n\n-EA

Joel, you need some help.  This is one of the easiest questions I have ever heard!  You should know this, man!  You're gonna fail your test if you keep cheating on here and don't actually figure out how it works.  Good luck, brotha'\n\nL = -2 or L(x) = -2

That is right. Just put them in a calculater to check. 2/9=0.22222222 and 8/36=0.2222222. Either they are wrong or you misinterpred the question and it was asking something else. The best way to solve a problem like that is to cross multiply. 2/9=8/? turns into 2*?=8*9.

The objective of this problem is to "solve for t" which means to isolate it on one side of the equation, hoping that only a number appears on the other side.\n\nBegin by distributing the (-6) factor through the left-hand side's other group of terms:\n\n-24 + 6t = 12t\n\n... being careful to let the two minus signs "cancel each other out" and become a + sign.\n\nNow, we hope to "collect like terms" -- that is, terms containing 't' -- on the right side.  Do so by subtracting 6t from both sides:\n\n-24 = 6t\n\nNow, finally, divide by the "coefficient of t" which is 6:\n\n-4 = t\n\nAnd there is your solution!\n\nMany teachers instruct you to "check your work" by substituting the "answer" back into the original problem, to make sure it is correct.  Let's do that here:\n\n(-6)(4-(-4) = 12(-4)?\n\nSimplify the left-hand slightly:\n\n-6 * (8) = -48?\n-48 = -48\n\nYes!  This yielded a true mathematical statement, hence our solution of t=-4 was correct all along.\n\nHope this helps!
