Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Evaluate the expression inside the parentheses, focusing first on multiplication.
  • Step 2: Perform the division inside the parentheses.
  • Step 3: Simplify the expression by completing the subtraction inside the parentheses.
  • Step 4: Subtract the result from 35.

Now, let's work through each step:

Step 1: Evaluate the multiplication inside the parentheses.
The expression is 32 3 \cdot 2 , which equals 6 6 .

Step 2: Perform the division inside the parentheses.
Substitute the result into 39:6 39 : 6 , which is 39÷6=6.5 39 \div 6 = 6.5 .

Step 3: Simplify the expression inside the parentheses by performing the subtraction.
The expression becomes 826.5=75.5 82 - 6.5 = 75.5 .

Step 4: Subtract the result from 35.
Hence, 3575.5=40.5 35 - 75.5 = -40.5 .

Therefore, the solution to the problem is 40.5 -40.5 , which corresponds to the first choice given in the possible answers as 4012 -40\frac{1}{2} .

Answer

4012 -40\frac{1}{2}
