Avery is buying exactly 15 fish. They can choose between angelfish and goldfish

1. Write an equation that represents how many angelfish Avery buys (a) if they buy g goldfish

2. How many angelfish does Avery buy if they buy 11 goldfish?

Respuesta :

Answer:

1. 15 - g = a

2. 4

Step-by-step explanation:

1. Because the total must sum to 15, a + g = 15. If we subtract g from both sides, we get 15 - g = a.

2. Plugging in 11 for g in the equation, we get a = 15 - 11 = 4
