12 + 10 + 11 equals 33
- log(2.3 X 10 -12 ) = 11.6 pH -----------------very little H + concentration in this solution.
4.8
No
It is: 12+(-4)-(-10) = 18
12 + 10 + 11 equals 33

10 plus 10 equals 20 20 divide by 10 equals 2 2 plus 10 equals 12
4.8
No
No, it equals 10.
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
It is: 12+(-4)-(-10) = 18
(x, y) = (3, 7) is a solution.
-10
x = 3 and y = 2
The Answer Is 42.
