positive 5
2 + 4 + 8 + 6 + 3 + 7 + 9 + 8 = 47
8 - 2 = 6 + (-7) = -1
9 + 6 + 9 + 6 + 9 + 8 + 5 + 2 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 99
2 + 5 is 7 + 6 =13 + 7 = 20 + 8 = 28 + 9 = 37 + 10 is 47.
6 plus 7 plus 8 equals 6 plus 8 plus 7, what property is that?That is the associative property.
7x+8=2 .....-8..-8 7x=-6 7x/7=6/7 x=6/7 In conclusion, 7(6/7)+8=2 I'm sure you meant: x = - (6/7) or -6/7 (not 6/7).
If you mean: 6*(7+8)*(6+7)+8 then it works out as 1178
The answer is 39.7 + 8 = 15 + 4 = 19 + 7 = 26 + 5 = 31+ 6 = 37 + 2 =39
1+2+3+4+5+6+7+8+9=37
6 plus 7
2 and 7/8 + 4 = 6 and 7/8
1+2+3+4+5+6+7+8+9= 45 :)
