-12 + 18 - (-15) = -12 + 18 +15 = 21
122 !
25 + 15 + 21 + 10 + 11 = 82
if this question is -6 times 3 plus 15 then = -21 if its -6 plus 3 plus 15 then = 12 if its -6 times 3 plus 1.5 then = -16.5 if it is -6 plus 3 plus 1.5 = -1.5
16, 12+15+21 = 48/3 = 16
13 + 21 - 7 + 12 = 15
-12 + 18 - (-15) = -12 + 18 +15 = 21
3+6+9+12+15+18+21+24+27+30+33+36 = 234
55 + 34 + 31 + 27 + 21 + 21 + 20 + 17 + 15 + 15 = 256
122 !
25 + 15 + 21 + 10 + 11 = 82
21 + 15 = 36
15+6 is 21. 13 + what is 21? 21 - 13 is 8 Eight
if this question is -6 times 3 plus 15 then = -21 if its -6 plus 3 plus 15 then = 12 if its -6 times 3 plus 1.5 then = -16.5 if it is -6 plus 3 plus 1.5 = -1.5
16, 12+15+21 = 48/3 = 16
2q + 21.
8 plus 7 is 15. 15 plus 6 is 21. :)
