Question

Question 110 pts (01.02 MC) Matt earns $30 for every lawn he mows and $12 for every hedge he trims. He uses the expression 12x + 30y 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) (10 points)

Answer 1

Explanation:

Part A: The coefficients in the expression are 12 and 30. The variables in the expression are x and y.

Part B: There are two terms in the expression, which are 12x and 30y. We know this because terms are separated by addition or subtraction signs. In this case, the terms are added together, so there are two terms.

Part C: The term in the expression that shows the total earned from trimming hedges is 30y. We know this because the coefficient 30 is multiplied by the variable y, which represents the number of hedges trimmed.
