Answer 2

To simplify the expression 0.2x(7-2y) + 2.3 - 0.3(y-6), you can follow these steps:

1. Distribute the 0.2x and 0.3 into their respective terms within the parentheses:

   0.2x * 7 - 0.2x * 2y + 2.3 - 0.3y + 0.3 * 6

2. Now, multiply the constants with the values inside the parentheses:

   1.4x - 0.4xy + 2.3 - 0.3y + 1.8

3. Combine like terms:

   (1.4x + 2.3 + 1.8) - 0.4xy - 0.3y

4. Add the constants together:

   4.5 - 0.4xy - 0.3y

So, the simplified expression is 4.5 - 0.4xy - 0.3y.
