25x (square) plus 40 plus 15 equals 680.
40 + 15% = 40 x (1 + (15/100)) = 40 x 1.15 = 46
It is: 40/10 = 15/100 = 4.15
25+15=40+9=49
40
15 + 15 + (10 * (1 / 2)) + (10 * (1 / 2)) = 40
If 40 plus x equals 25 then x is equal to -15.
it would be -1
16/40 + 15/40 = 31/40
25+15=40
The answer to 25 plus 40 take away 15 H take away -80 equals -40. This is a math problem.
-32/40 - 15/40 = -47/40 = -1 and 7/40
