Answer 2

It looks like you've provided a series of mathematical expressions and assignments. Let's break down each part step by step:

A) (3 = -1) + 12.5

It seems like there might be a misunderstanding here. The expression (3 = -1) is not a valid mathematical operation. In mathematics, the equal sign (=) is used for equality comparisons, not for arithmetic operations. If you're trying to add 12.5 to something, you can just write it as:

Result A = 12.5

B) (2 - 1.5) + (2.5 - 13) * (3 - 0.25)

Let's simplify this expression step by step:

1. 2 - 1.5 = 0.5
2. 2.5 - 13 = -10.5
3. 3 - 0.25 = 2.75
4. -10.5 * 2.75 = -28.875
5. 0.5 + (-28.875) = -28.375

Result B = -28.375

It seems like you're mentioning that if the answer to B) is -28.375, you're giving 60 points.

Please note that the expression (3 = -1) is not mathematically valid. If you have a different intention or need further assistance, please provide more context or clarification.
