Answer :
To simplify the expression [tex]\(8.5 + (12 + 4) \times 2 - 7\)[/tex], follow these steps:
1. Calculate inside the parentheses:
Start by adding the numbers inside the parentheses:
[tex]\(12 + 4 = 16\)[/tex].
2. Multiply the result by 2:
Take the result from step 1 and multiply it by 2:
[tex]\(16 \times 2 = 32\)[/tex].
3. Add 8.5 to the multiplication result:
Add 8.5 to the result from step 2:
[tex]\(8.5 + 32 = 40.5\)[/tex].
4. Subtract 7 from the result:
Finally, subtract 7 from the step 3 result:
[tex]\(40.5 - 7 = 33.5\)[/tex].
Therefore, the simplified value of the expression is [tex]\(33.5\)[/tex].
