75x + 25y
Part A: coefficients = 75 & 25 variables = x & y
Part B: Terms = 2 - term 1: 75x- term 2: 25y
Terms are the different parts or groups of an equation. Therefore, 75x is one term and the other is 25y. They are each a part of the equation. Without them you wouldn't have an equation at all.
Part C: Pizzeria pay = 75x because that is how much she makes each shift she works.
