It equals x2 - 34

If 40 plus x equals 25 then x is equal to -15.

x=34

A number "m" plus 40 equals 60. Therefore, 60 minus 40 equals m. m therefore equals 20.

b = 40 - a, c = 42 - a so b + c = 40 - a + 42 - a, ie 82 -2a = 34 so a = 48/2 ie 24 b = 40 - 24 ie 16 and c = 42 - 24 ie 18

The answer is: 23.2 plus 16.8 equals 40

It equals 40. If you are prepared for it, it also equals 39.999... (repeating).

-9h-6+12h+40 = 22 3h+34 = 22 3h = 22-34 3h = -12 h = -4

The solution to this equation is that h is equal to -4. You can substitute this value for h into the equation to get -4 x -9 - 6 plus 12 x -4 plus 40 equals 22, or 36 - 6 plus - 48 plus 40 equals 22.

34 + 6 = 40

36 + 35 + 40 + 40 + 40 + 40 + 40 = 271

10y plus 40 equals 50y.

-9h - 6 + 12h + 40 = 22, simplifying this gives12h - 9h + 40 - 6 = 223h + 34 = 22, taking 34 off both sides gives3h + 34 - 34 = 22 - 343h = -12, thush = -12/3 = -4

In equations, this is how to figure it out. -34+ x =6 -34+ x - -34=6- -34 x=40 (subtracting a negative number is actually adding it's absolute value, its distance from 0)

When you add 34 plus 4 plus 2, you get an answer of 40.

20 plus 20 equals 4020 plus 20 = 40

ninety 4 + 6 = 10 30 + 50 = 80 10 + 80 = 90 or 56 + 4 = 60 60 + 30 = 90 same as 34 + 6 = 40 40 + 50 = 90

11 + 29 = 40

25x (square) plus 40 plus 15 equals 680.

10 plus 20 plus 30plus 40 plus 50 equals 150 because 50 plus 40 equals 90 plus 30 =120+20= 140 then + 10 = 150
