Answer :
To simplify the expression [tex]\(8.5 + (12 + 4) \times 2 - 7\)[/tex], we can follow these steps:
1. Calculate the expression inside the parentheses: [tex]\( (12 + 4) \)[/tex]
- Add 12 and 4:
[tex]\[
12 + 4 = 16
\][/tex]
2. Multiply the result by 2:
- Multiply the result from step 1 by 2:
[tex]\[
16 \times 2 = 32
\][/tex]
3. Add 8.5 to the multiplied result:
- Add 8.5 to the result from step 2:
[tex]\[
8.5 + 32 = 40.5
\][/tex]
4. Subtract 7 from the result:
- Subtract 7 from the result in step 3:
[tex]\[
40.5 - 7 = 33.5
\][/tex]
Thus, the simplified value of the expression is [tex]\(33.5\)[/tex].
