Answer 3

The equation you provided seems to have an error in its formatting, which makes it difficult to understand. However, I will try to help you understand how to evaluate expressions involving addition and parentheses.

Let's reformat the expression to make it more clear: 15 + (-12 + 4.5) = 7.5

To solve this expression, follow these steps:

1. First, evaluate the expression inside the parentheses: (-12 + 4.5) = -7.5
2. Now, the equation becomes: 15 + (-7.5) = 7.5
3. Finally, perform the addition: 15 - 7.5 = 7.5

So, the result is indeed 7.5.
