Answer:11.4 - 11.1y. I think
Step-by-step explanation:To simplify the expression 4 - 2.2y + (-8.9y) + 7.4, we can combine like terms. Like terms are terms that have the same variable raised to the same power. In this expression, the like terms are the terms with "y". First, we have -2.2y and -8.9y. These terms have the same variable "y" and are both negative, so we can add them together. When we add -2.2y and -8.9y, we get -11.1y. Now, our expression becomes 4 - 11.1y + 7.4. Next, we can combine the constant terms, which are the terms without any variables. We have 4 and 7.4, which we can simply add together to get 11.4. Our expression now becomes 11.4 - 11.1y. Therefore, the simplified form of 4 - 2.2y + (-8.9y) + 7.4 is 11.4 - 11.1y.
