Answer 3

It seems like you want to simplify the expression:

0.3x + 0.8y + 1.5x + 1.2y

To simplify this expression, you can combine like terms. Like terms are terms that have the same variables raised to the same powers. In this case, you can combine the x-terms and the y-terms:

(0.3x + 1.5x) + (0.8y + 1.2y)

Now, add the x-terms and the y-terms separately:

(0.3x + 1.5x) = 1.8x (0.8y + 1.2y) = 2.0y

So, the simplified expression is:

1.8x + 2.0y

You can also write it as:

1.8x + 2y
