Question

Beau´s aquarium has 12 fish.Five of the fish are guppies. Which equation can be used to be determine the number of other fish in his aquirium

Answer 1

12 = 5 + x

Explanation:

Total fish in the aquarium = 12

Number of guppies fish = 5

Number of other fishes = x

Total fish in the aquarium = Number of guppies fish + Number of other fishes

12 = 5 + x

Subtract 5 from both sides

12 - 5 = 5 + x - 5

7 = x

x = 7

Number of other fishes = x = 7
