Question

In each expression below, identify the coefficient, constant, and variable. a. 7 + 9 b. 6 – 5 c. 4.5 – 2.7

Answer 1

-1 and 1/3

Explanation:

I replaced each variable with 1. Other than that I just guessed and got it right lol

Answer 2

The variable is the letter like x or y. The coefficient is the number next to the variable like the 2 in 2x or if its just x it would be 1. The constant is the number by itself usually at the end.

Example 2x+5

Variable is x constant is 5 and coefficient is 2. Sorry i didn't answer the actual question and just told you how to find it but those expressions don't have any of these things.
