### Instruction: If xy > 0, 1/x + 1/y = 6, and 1/xy = 12, then (x+y)/6 = ?
Answer Choices: (A) 1/12 (B) 1/6 (C) 1/5 (D) 5 (E) 6.### Response: Let's think about the multi-choice question step by step.
(1/X+1/Y)=6 canbe solved as {(x+y)/xy}=12. Substituting for 1/xy=12, we get
x+y=6/12
==> (x+y)/6= 6/(12*6)=1/12.
The answe is A
