55 + 34 + 31 + 27 + 21 + 21 + 20 + 17 + 15 + 15 = 256
25 + 15 + 21 + 10 + 11 = 82
21 + 15 = 36
15+6 is 21. 13 + what is 21? 21 - 13 is 8 Eight
2q + 21.
8 plus 7 is 15. 15 plus 6 is 21. :)
it would be 21. I think the answer is -22. Because -16 + -21= -37 + 15= -22
13 + 21 - 7 + 12 = 15
x = 15 as 4*15+6 = 66 3*15+21 = 66 or an easier way to do it 4x - 3x = 1x 21 - 6 = 15 1x = 15
15
