Answer 3

Let's simplify the expression step by step:

1. Start with the innermost parentheses:

   -2.6 - 6.5 = -9.1

2. Next, simplify the expression within the second set of parentheses:

   -(-3.8 - 7.3) = -(-11.1) = 11.1 (since the negative of a negative is positive)

3. Now we have the expression:

   -3.5 - 9.1 2.7 - 11.1

4. Perform the subtraction and multiplication operations from left to right:

   -3.5 - 9.1 = -12.6 -12.6 * 2.7 = -34.02

So, the final result is -34.02.
