70\n\ndivide 30 by a half equals 60

1/2*1/4*1/10 = 1/80\n\n=> 1/80 of 800 = 800/80 = 10\n\none half of one quarter of one tenth of 800 is 10.

Set it up: x=1/y which simplifies to x/y. So if y=30 when x=2, then 2/30=0.066667 When y=600, then x/600=0.066667; multiply 0.066667 by 600 for your answer of x=40. Good luck!

1= 1/2 +1/2\n\nThat is two "1/2"s\n\nThat was easy.

70\nUnless by 1/2 you mean divide by half of 30, the it's 25

Not necessarily.  If the answer to a division problem is 7.5, then the answer is 7 and a half (half of what you're dividnig by).\n\nExample- 15 divided by 2 is 7.5, but the remainder in this problem is 1, not 5 (1 is half of 2).

1/(x-2) - 1/(x+3) = 1/10\nMultiply through by your LCD, 10(x - 2)(x + 3), giving\n10(x + 3) - 10(x - 2) = (x - 2)(x + 3)\n10x + 30 - 10x + 20 = x^2 + x - 6\nx^2 + x - 56 = 0\nFactor and solve for x

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

Find every number between 101 and 999 that is divisible by 7 and then add them together.  Hmmm......like I really am going to do that.

If XY=1 then,\nJack :\n1/30+1/10\n=1/30+3/30 \n=4/30\n=2/15\nand Sandy:\n1/20+1/20\n=2/20\n=1/10\n \nJ:S=2/15:1/10\n=30*2/15:30*1/10\n=4:3\n\nJack would wast more times than Sandy,\nSandy will finish first.

Y+X=10^26\nX*.02=Y\n\nSo:\n51X/50=10^26\nX=5*10^27/51\nY=10^26/51

The easiest way to do this in an easy way to understand is to pretend that you have 100 dollars and do the math:\n\n$100 + 10% = $110\n\n$110 - 25% = ???\n\n25% of $110 is $27.50 so subtract this from $110.\n\n$110 - $27.50 = $82.50

multiply 5,000 x .30 = 1,500 Then you subtract it from the 5,000 which equals 3,500. Just in case you need to do it again.

$10,000^(1+(.068/10))^(27*10)=\n$62,325.51

101 - 10^2 = 1... just raise the 2 up a bit.\n\nhope this helps :-)

11 1/10 because:\n3 1/6 = 3 5/30\n2 3/5= 2 18/30\n5 1/3= 5 10/30\n\n(30 is the LCD)\n\nWhen you add them all together you get 10 33/30 which reduces to 11 1/10

You simply add all numbers together and divide by the number that was the number of numbers you added together. \n\nexample 60 20 30= 110 110 divided by 3
