6 - (-9) = 15 15 + 2 = 17 17 - 4 = 13 is the answer.
(4/15) + (6/20) = 16/60 + 18/60 = 34/60 = 17/30
14Another answer:-17+17-14+(2*6)+2 = 0
17 + 13 + 12 + 12 + 6 + 9 = 69.
15 x 6 or the long way is 90
6p + 12q + 18r = 6 (p + 2q + 3r)
-12q+4=q-6 4-6=q+12q -2=13q q=-2/13
Get the 'q' together on one side and everything else on the other side. Add 12q to both sides --> 12q - 12q + 4 = 12q + 8q -6 --> 4 = 20q -6 Add 6 to both sides --> 6 + 4 = 6 + 20q - 6 --> 10 = 20q Then divide both sides by 20 --> 10/20 = 20q / 20 ---> 1/2 = q Substitute q = 1/2 into the original equation to make sure you did it right.
6 - (-9) = 15 15 + 2 = 17 17 - 4 = 13 is the answer.
8/10 plus 2/6 = 17/15 or 1 and 2/15
17 + 6 = 23
17 + 6 + m
(4/15) + (6/20) = 16/60 + 18/60 = 34/60 = 17/30
9
5 + 6 + 6 = 17
6 + 6 + 5 = 17
8 plus 7 is 15. 15 plus 6 is 21. :)
