Question

Cory earns $20 for every lawn he mows and $9 for every hedge he trims. He uses the expression 20x + 9y to keep track of his earnings. Part A: Identify the coefficients and variables in the expression. (3 points) Part B: How many terms are in the expression, what are they, and how do you know? (4 points) Part C: Which term in the expression shows the total earned from trimming hedges? (3 points)

Answer 1

Explanation:

Part A: A coefficient is a number stuck to a variable (a variable is the letter). Our coefficients are 20 and 9

Part B: There are 2 terms in our expression. A term is a combination of numbers and letters stuck together by multiplication, and terms are separated by addition or subtraction.

Part C: The term that is the expression representing the total earned from trimming is 9y, since he earns $9 for every hedge he trims. The 20 goes with the lawns he mows.
