Marlin has a fish tank that contains 38 fish. There are 9 goldfish and f other fish.

Question

Plz help me in this math homework. thank you for you time and have a nice evening 

Answer 1

I am assuming that the question is: find f, the number of other fish in the tank.

 

Total number of fish in the tank = 38

 

Number of goldfish = 9

 

Number of other fish = 38 - 9 = 29

 

Therefore there are 29 other fish in the tank = f

 

Checking: total number of fish in tank = number of goldfish + number of other fish = 9 + 29 = 38
