Final answer:
To simplify the expression (3+7, 5+11) = (, ) / 2, perform the operations inside the parentheses first and then divide the sum by 2. The simplified answer is 13.
Step-by-step explanation:
To simplify the expression (3+7, 5+11) = (, ) / 2, we need to perform the operations inside the parentheses first. So, (3+7) becomes 10 and (5+11) becomes 16. Then, we divide the sum of these two numbers by 2. Adding 10 and 16 gives us 26, and dividing it by 2 gives us the final answer of 13.
