Question

simplify the expression: 3.5 + (5.3 + y) =

Explanation:

Step1: Apply the associative property of addition

The associative property of addition states that \( (a + b) + c = a + (b + c) \). So we can remove the parentheses and add the numbers first: \( 3.5 + (5.3 + y) = (3.5 + 5.3) + y \)

Step2: Calculate the sum of 3.5 and 5.3

\( 3.5 + 5.3 = 8.8 \)

Step3: Combine the results

After calculating the sum of the numbers, we have \( 8.8 + y \)

Answer:

\( 8.8 + y \)
