Answer 3

Let's solve each of the given expressions one by one:

1. 1.3 + (-6) = -4.7 Adding a positive number (1.3) and a negative number (-6) results in a negative number (-4.7).

2. 2.0 - 5 = -3.0 Subtracting 5 from 2.0 gives us -3.0.

3. 3.0 + (-7) = -4.0 Adding a positive number (3.0) and a negative number (-7) gives us -4.0.

4. -(-1) - 9 = 8 Simplifying the expression, we have -(-1) = 1, so the expression becomes 1 - 9 = -8.

5. -7 - (-4) = -3 Subtracting a negative number is the same as adding its positive counterpart. So, -7 - (-4) can be rewritten as -7 + 4, which equals -3.
