Answer :
We start with the expression
[tex]$$8.5+(12+4) \times 2-7.$$[/tex]
First, evaluate the parentheses:
[tex]$$12+4=16.$$[/tex]
Next, multiply the result by 2:
[tex]$$16 \times 2 = 32.$$[/tex]
Then, add 8.5 to the product:
[tex]$$8.5 + 32 = 40.5.$$[/tex]
Finally, subtract 7:
[tex]$$40.5 - 7 = 33.5.$$[/tex]
So, the simplified value of the expression is [tex]$\boxed{33.5}$[/tex].
