Help with a math problem!?

The extra 7% must be the same as the 2240 yen (though it's awkwardly put).\n\nLet Y and T be what the store made yesterday and today. \n\n0.07Y = 2240\nT = 1.07Y\n\nSo \n\nT = 1.07*2240/0.07 = 34240

are u sure its x2? shouldn't it be 2x+10x=(a number) usually there is a number at the end of the equation and u have 2 solve for "x". add details to ur question and then i may be able 2 help u.

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.

This is not an equation.  Its garbage.  Both side of the equation have to equal each other.\n-35=.000075 this does not compute

try to follow\n\nx/2-10=a\na/2-4=b\nb/2-2=6\n\nsolve and substitue\nb=16\na=40\nx=100 --the original amount\n\nhope that helped

The original problem:\n    -11 ( 3/2 ) ( 0.12 ( -12 ) )\nSolving for the innermost quantity:\n    -11 ( 3/2 ) ( -1.44 )\nThe two negatives cancel each other out:\n    11 x ( 3/2 ) x 1.44\nBasic multiplication:\n    23.76

With this given data, it is not possible\n\nalthough the area is totalling to be 70 for both cases (7*10 and two pieces of 8*8 + 1*6) but with one division only, this is not possible\n\nPLEASE DO LET ME KNOW IF THERE IS SOME SOLUTION (i found it very interesting)

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.

it would be 22 choose 4 =22!/(4!18!) minus the ways in which Mr and Mrs Math can be together = 20 choose 2 = 20!/(2!18!)\n=(22.21.20.19)/(4.3.2)-...\n...(20.19)/(2)\n=((20.19)/2).((22.21/4.3)-1)\n=190.75/2\n=7125\nSorry had to two line one bit due to Yahoos dodgy cutting off of things

So lets start with the first one. Make a division problem with 9.0 on the outside and 0.9 on the inside. 9.0 does not go into 0 but does go into nine. Raise the decimal and the answer is ten. It's a bit difficult to explain but here's your answers and when you go in next time ask your teacher for help::\n1. 10 \n2. 8\n3. 4.7\n4. 3.2\nOkay theres a few for you and you should be able to figure out the rest. For the next part you take what x is equal to and divide it by 1.2. So for\n13. 40.8/1.2=34\nAnd do the same for the rest!!\nGood luck!

just plug the numbers in.  if y=8, and x=2, \nits 8=a(2^2)\nso 8=a(4)\nso a=2.\nhope that helps!
