Final answer:
The value equivalent to 48 ÷ ((2 + 6) × 2) - 1 is B) 2.
Step-by-step explanation:
To solve this problem, we need to follow the order of operations (also known as PEMDAS or BODMAS). 
First, we calculate the expression inside the parentheses: 2 + 6 = 8. 
Next, we multiply the result by 2: 8 × 2 = 16. 
Finally, we divide 48 by the result: 48 ÷ 16 = 3. 
After that, we subtract 1: 3 - 1 = 2. 
Therefore, the value equivalent to 48 ÷ ((2 + 6) × 2) - 1 is 2.
