A. 1
B. 3
C. 9
D. None

The correct answer is 1. Following the order of operations: 9 - (3 ÷ 1/3) + 1 = 9 - 9 + 1 = 1.

By using PEMDAS: Parentheses: Simplify inside the parentheses first. There is nothing to simplify inside the parentheses themselves, but we should identify that

3(2) means

3×2.

3(2)=3×2=6

So the equation becomes:

5+2×6÷6

Multiplication and Division: Next, we perform multiplication and division from left to right.

First, perform the multiplication:

2×6=12

Then, perform the division:

12÷6=2

Now the equation is:

5+2

Addition: Finally, perform the addition:

5+2=7

So, the simplified value of the equation is:

5+2×6÷3(2)=7
