NO! Top guy didn't do that right, look below!\n\nn/2-8=7\nn/2=15\n15x2=n\n30=n\n any more algebra, IM me . . i like it

5 * 3 = 15\n\n15 - 7 = 8\n\n8 * 3 = 24

8 numbers can be placed  in 8! ways.\nExchange the three two's gives no new numbers, so divide by 3!\nExchange the two six's gives no new numbers, so divide by 2!\n8! / ( 3! x 2! ) = 1680\n\nTh

(7/x) - (8/5x) = ?\n\n[(5*7) - 8]/ 5x = ?\n\nAnswer: 27/5 x

To show you how to do it yourself..\n\nfor 8/7: 7 "goes into" 8 once so separate it as 7/7 + 1/7, 7/7 becomes "1" and "1/7" remains as a fraction.\n\nTherefore "8/7" becomes "7/7 + 1/7" which becomes 1 1/7.\n\nSimilarily, 38/6 becomes 36/6 + 2/6 which becomes 6 2/6.\n\nYou get to do the rest.... happy learning!

First: 8 + 2*5 -24 = 8 + 10 - 24 = 18 - 24 = -6\nSecond: 6*2 = 12\nFinally: -6/12 = -1/2 \nif the question was (8 + 2*5 -24)/(6*2)

It's multiple choice, so all you really need to do is start plugging numbers in and see if they work:\ng(7) = 2(343) -11(49) + 8(7) + 21\ng(7) = 686 - 539 + 56 + 21 =/= 0\n\ng(1) = 2(1) - 11(1) + 8(1) + 21\ng(1) = 2 - 11 + 8 + 21 =/= 0\n\ng(7/2) = 2(343/8) - 11(49/4) + 8(7/2) + 21\ng(7/2) = 343/4 - 539/4 + 112/4 + 84/4 = 0\n\nThus, d is the right answer.

(32 + 18 - 45 x 3) / 5 - 7 x 2 = ?\n\n-31

Convert everything to a common denomoinator, 32 in this case.\n1/2 = 16/32  and 5/8 = 20/32\n\nYour choices:\n3/4 = 24/32\n13/32 = 13/32\n 7/16 = 14/32\n 9/16 = 18/32 < == Your answer\n 1/4 = 8/32

just go straight across.\n\nlike:  3/8 x 2/3 = 6/24 which simplifies to 1/4\n\nBecause on the top: 3x2=6 and on the bottom: 8x3=24\nThen 6 goes into itself once and into 24 four times: 1/4

8 because 7/8 cannot be reduced to anything more simple, so the simplest fraction that can be multiplied to 1/4 to get a multiple of 8 on the bottom is 2/2 resulting in 2/8.  Therefore the lcd is 8

Add them... 8+7+7+5+3+2+2= 34 and divided by 7\nYyou have 34/7=\nYou know 4x7= 28 so you need 6 more to reach 34\nso you have 4 and 6/7

7 1/4=7.25\nRounded=7 (Round down because "2" is less than 5)\n\nThe nearest whole number is 7.\n\nKenlas, if you had 7 3/4, and you dropped the remainder, it wouldn't be the nearest whole number--8 would.

(x/x-2)-(x+1/x)=8/(x^2-2x)\n[x(x)-(x-2)(x+1)]/[x(x-2)]=8/[x(x-2)]\nx^2-(x^2-2x+x-2)=8\nx^2-x^2+x+2=8\nx=8-2=6

7+n=9+7\nfirst subtract 7 from both sides\n7+n=9+7\n-7   -7\nso now we have \nn=9\nThe answer is 9!
