Answer 2

To simplify the expression (4a - 2) × 0.5 + (3 - 5a) × (-0.4), you can follow these steps:

1. Distribute the constants to the terms inside the parentheses: (4a * 0.5 - 2 * 0.5) + (3 * (-0.4) - 5a * (-0.4))

2. Simplify each term:

   (2a - 1) + (-1.2 + 2a)

3. Now, you can combine like terms:

   (2a + 2a) + (-1 - 1.2)

4. Add the like terms:

   4a + (-2.2)

5. Finally, combine the constants:

   4a - 2.2

So, the simplified expression is 4a - 2.2.
