I must know!!!!!!\n\nand if you know the answer to 4/5 = (-9/4) - 7/10 x\nthat would be nice\ni just can't get it...

Suppose you have a set of numbers:\n\n0, 1, 1, 2, 3, 4, 6, 8, 9, 11, 15\n\nThe median is the middle number when put in least to greatest: 4\n\nThis breaks your list into two halves: 0, 1, 1, 2, 3 and 6, 8, 9, 11, 15.  Your upper quartile is the median of the greater half: 9.  Likewise, your lower quartile is the median of the lower half: 1.\n\nIn the event you have two numbers for a median, take the average of the two and that becomes your median.  In the above example, if you only had 6, 8, 9, 11 for your upper half, your median would be the average of 8 and 9, or 8.5.\n\nAs for your second question (assuming that x belongs in the numerator):\n\n4/5 = (-9/4) - 7x/10\n4/5 + 9/4 = -7x/10\n16/20 + 45/20 = -7x/10\n61/20 = -7x/10\n61/2 = -7x\nx = -61/14

3/4(5 1/3-8/9)=1/2(5 1/3+2/3\n3/4(48/9-8/9)=1/2(6)\n3/4(40/9)=3\n10/3=3\n3 1/3=3\nfalse

1) -2 x (2/5 -2p)\n    =4/5+4p            after multiplying through by -2\n\n2) 1 x (9/20 -p)\n    =9/20-p              after multiplying through by +1\n\nThis has started you off you should be able to solve now!

X+Y=5\n\nHence Y=(5-X)\n\nHence Y/4 = 5/4 - X/4\n\nHence your first equation is\n\n(X^2)/6-(5/4-X/4)=1\n\nX^2+3X/2-27/2=0\n\n2x^2+3x-27=0\n\nx= (-3 +/- 15)/4\n\nx= 3 or x= -9/2\ny= 2 or y= 19/2\n\nSo either x=3, y=2 or x= -9/2, y= 19/2.\n\nP.S. I assumed that x^2/6 means (x^2)/6 and not x^(2/6) which would be much more difficult.\n\nGood luck.

3/x-4 = 5/x\ncross multiply:\n 3x= 5x-20\n-5x -5x\n\n-2x=-20\ndivide -2 on each side x=10

[(7x^3)(-x^7)]/14x^4\n= (-7x^10)/14x^4\n= -x^6/2

x = -4\n10points thank u!

10 - 7 = 3\n\ntherefore 3 x 4 (for the 1/4) = 12\n the number is 12

X/4=9/3\n=>X=4*9/3 = 36/3 = 12\n\n7/5=X/3\n=> X=3*7/5 = 21/5 = 4.2

The answer is 1/2. To solve it... use algebra. Use X to represent the unknown fraction. Turn the word problem into a numerical expression. It will look like this: 4(X/5) x X = 1/5.    the little x is times. simplify and you get 4X^2/5= 1/5. then simplify again and you get 4x^2=1 Then x^2= 1/4 then x=1/2 ta da!

5/4x + 1/x = 3/4\n\nFirst, multiply everything by 4 to get rid of the denominators.\nSo now you have:\n\n5/x + 4/x = 3\nnow multiply everything by x to get:\n5 + 4 = 3x\n \n9 = 3x \n\ndivide each side by 3\nx = 3\n\nnow check your answer by replacing x with 3

Okay first of all you write it like this...\n(3.5-1.666~)/1.333~\nUsing fractions is easier in this case, so here it is.\n7/2-5/3= 21/6-10/6=11/6 division by a fraction is multiplication by the inverse, so multiply 11/6 by 3/4 and you get 33/24, which can be reduced to 11/8 (eleven-eigths)\n\nBy the way, it's spelled "parenthesis"

y/=-8 = 11\nMultiply both sides by -8\ny = 11(-8)\ny = -88\n\n4/5 = 16  This is simply not true.\nAssuming you left out a variable, then\n(4/5)x = 16\nMultiply both sides by (5/4)\nx = 16(5/4) = 80/4\nx = 20\n\n-x/6 = 9\nMultiply both sides by -6\nx = 9(-6)\nx = -54\n\n1/9 = /2/7  does not make sense

Ask youself "Does 4/40 = 8/80 ?"\n4/40= 1/10, and\n8/80 = 1/10\nSo the answer is Yes.

9 + 4r -7= 0\n-9              -9\n\n4r - 7 = -9\n     +7   +7\n\n4r      = -2\n\n4r/4   = -2/4\n\nr= -2/4 reduce it by dividing the numerator and denomenator by 2\n\nr = -1/2(solving for r)  or you could just leave it as 2+4r(simplify)\n\n\n5 + (-12t) + 8t= 0\n-5                     -5\n\n-12t + 8t = -5\n\n-4t = -5\n\n-4t/-4 = -5/-4\n\nt= 5/4  reduced by dividing 4 into 5\n\nt= 1 1/4(solving for t) or leave it as 5-4t(simplify)

Probably easier to show by example.\n4x2+8-:-4-1 (-:- = divide)\nmultiply any numbers first, then divide, then add and subtract.\n\nYou could add brackets in if that helps you.\n(4x2)+(8-:-4)-1 = 9

You again???? If you keep having people do your homework, you wont learn! \n9.8 + x/5 = 10.4\n\n  x/5 = 10.4 - 9.8\n  then to eliminate that 5 \n 5 *  x/5 = 0.6 * 5\n\n    x= 3\nthen substitute to check answer
