22
12 the correct answer is 12.
12
12 + 14 + 3 = 29
3 + 12 + 16 = 31
12 - 8 + 3 + 5 = 12
(12 + 8) + 3 = 12 + (8 + 3)20 + 3 = 12 + 1123 = 23 ■
3 + 6 + 9 + 12 = 30
It evaluates to: 12+(-1)+(-1)+3 = 13
So, 3 + 12 = n + 3. Subtract 3 from both sides of the equation and get 12 = n or n = 12 if you prefer.
12
1/5
2/12 + 2/12 + 4/12 + 9/12 + 6/12 = 23/12 or 1 and 11/12
