Answer :
We start with the expression:
[tex]$$8.5+(12+4)\times 2-7.$$[/tex]
Step 1: Evaluate the parentheses
Calculate the sum inside the parentheses:
[tex]$$12 + 4 = 16.$$[/tex]
Step 2: Multiply by 2
Multiply the result by 2:
[tex]$$16 \times 2 = 32.$$[/tex]
Step 3: Add 8.5
Now add 8.5 to the result:
[tex]$$8.5 + 32 = 40.5.$$[/tex]
Step 4: Subtract 7
Finally, subtract 7 from the current total:
[tex]$$40.5 - 7 = 33.5.$$[/tex]
Thus, the simplified value of the expression is:
[tex]$$\boxed{33.5}.$$[/tex]
