I need help with math x8 / x2 =?

Since you're dividing two monomials with the same base (x), you subtract the exponents so the answer is x^6. \n\nHope this helps ;-)

Easy. 40 divided by 2 is 20. Take half of 40.  OR 40x0.5

interesting!!!!  \n\n                 9x8 =72  7+2 =9\n                 9x9 =81  8+1 =9\n                 9x3 =27  2=7 =9

8 is the integer.\n2x-8/x = 15\n2(x*x)-8 = 15x\n2(x*X)-15x-8= 0\n2(x*X)-16x+x-8 = 0\n2x(x-8)+1(x-8)= 0\nx = 8

If you are sloving for X then anything greater than 2 will work. basically it is 6 time what (X) will be greater than 12. Well 6x2=12 so that won't work.

Assuming you mean x-2*9=54\nx-2=54/9\nx-2=6\nx=6+2\nx=8\nyour answer is 8\n8-2*9=54

x2=x1/2, y2=y1+x1/4, z2=z1+x1/4\nx3=x2+4, y3=y2-8, z3=z2+4\nx4=x3+z3/4, y4=y3+z3/4, z4=z3/2\nx4=y4=z4=16\nz3=z4*2=32\nx3=x4-z3/4=8\ny3=y4-z3/4=8\nx2=x3-4=4\ny2=y3+8=16\nz2=z3-4=28\nx1=x2*2=8\ny1=y2-x1/4=14\nz1=z2-x1/4=26\n\nSo the ages are 8, 14 and 26

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

(4/x-8/y)/(24/xy)\n=(4y-8x/xy) * xy/24\n= 4(y-2x)/xy * xy/24\n=(y-2x)/6

ok.\n6/x-8 >= 5\n\n6 >= 5 (x-8)\n\n6 >= 5x-40\n6+40 >= 5x\n\n46 >=  5x\n\n46/5 >= x\n\nx <= 46/5

Solving the problem stepwise -\n(x - 8 ) ( x - 2 )\n= x(x-2) - 8(x-2)\n=x^2-2x-8x+2\n=x^2-10x+2\n\nThese two sites will help you for the concepts.

Forty.\nCross multiply/divide  \n5/8=25/x\nmultiply both sides by x and both sides by 8\nyou get\n5x=25 times 8\n\nx = (25x8)/5  or x=25/5 x 8 or x = 5 x 8

x/(x-8) + 7 = 8/(x-8)\nMultiply everything by (x-8)\nx + 7(x-8) = 8\nDistribute the 7\nx + 7x - 56 = 8\nCombine x and 7x\n8x - 56 = 8\nAdd 56 to each side\n8x = 64\nDivide both sides by 8.\nx = 8\n\nNote that x-8 cannot equal zero, but we just found x to be 8.\nThat means x-8 = 8-8 = 0\nThus, we have no solution.

T=m1*-9.8+m1*a\nT=m2*a--m2*-9.8\n\nset them equal and solve for a\n\ntrust me, i had a test on this today

a.   First multipy -2 times (x-4) to get -2x+8\nb.   Then 5-2x+8 to get -2x+13\nc.   then 3 times (-2x+13) to get -6x+39\nd.   then add 6x to both sides to get 39=8x+9\ne.   subtract 9 on both sides to get 30=8x\nf.   divide both sides by 8 to get x=(30/8) or (15/4)
