I need help with a math problem...?

120mi / x mph = 120mi / (-2x mph) - 3hrs\n120/x = -120/(-2x) - 3\n120/x = (120 + 6x)/(2x)\n(2x)(120) = (x)(120 + 6x)\n240x = 6x^2 + 120x\n6x^2 - 120x = 0\nx^2 - 20x = 0\nx(x - 20) = 0\nx = 20\n\n20 mph

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~

It depends on the type of math problem.  I can't really give you specifics without knowing more information.  Feel free to email or IM me and I'll try to help you.

What math test do you take?  I'm in Algebra 1 and I only remember 1 question.  It's impossible.\n\nSomeone has a total of 100 coins in dimes and quarters.  The total value adds up to $14.05. How many quarters does she have?\n\nA) 27 (I chose this-it's a dollar off)\nB) 40\nC) 56\nD) 79 (I forget-it's way too high)\n\nWell, that's all I have.  Bye bye!\n\nThanks to the guy who solved that.  I won't get a zero now!

Subract the two terms on the left giving:\n-2t < 16\n\nAdd 2t to both sides giving\n0 < 16 + 2t\n\nSubtract 16 from both sides\n\n-16 < 2t\n\nDivide both sides by 2\n\n-8 < t

half it then times it by 2! that will give u the answer

ignore the decimals when u originally do the problem, then however many deciams there are in both of the decimals you're multiplying is how many there will b in the answer. i.e. if you multiply 6.78x4.234 together the answer will have 5 numbers behidnthe dceimal point

Have you tried these?  Surely you've been told that division by 0 isn't possible, so there's your answer for 7.  I'm not doing any others on Yahoo answers (too many at once), but if you really need help and are willing to do as much as possible for yourself I'll help you if you email h_chalker@yahoo.com.au, but nasty Maths teachers like me won't just hand you 7 answers on a plate!

Just put each number in for x and see what the answer is.  Example : -11/2 + 75 = -5.5 + 75 = $69.50 a unit.

Ok...\nI see what you are doing...\nYou merely substitute the number in for x...\nso the problem becomes 6-2*(-1)\n6+2\n8

Next time just type your math equation into Google and it will do the math for you.\n\n15

Do a Yahoo search.  Enter "Homework help, math."  There are bunches of web sites.  Good luck.
