Answer: 252 Boys, 168 Girls

Step-by-step explanation:

420 would be 100% of the school students.

If you wanna find the number of girls, you need to divide 420/100 in order to get 1% and then multiply it by 40.

So then you would get

420/100 x 40 = 168

Then in order to get the boys just subtract 168 from 420

420- 168= 252

Each week, Abigail earns $75 for every shift she works at the pizzeria and $25 for every dog-walking job. She uses the expressio

Fed [463]

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.

- Hope this helps. =)
