Question

Fido weighs 26 pounds more then fifi fifi weighs12 pounds less than rover if the sum of their weights is 71 how much does fifi weight

Answer 1

11 pounds

Explanation:

Let the weight of Rover is x pounds.

As Fifi weighs 12 pounds less than Rover, so,

The weight of Fifi = x-12...(i)

As Fido weighs 26 pounds more then Fifi, so,

The weight of Fido = (x-12)+26=x+14.

As the sum of their weights is 71, so,

x+(x-12)+(x+14)=71

x+x-12+x+14=71

3x+2=71

3x=71-2=69

x=69/3

x=23

From equation (i), the weight of Fifi = 23-12=11 pounds.

Hence, the weight of Fifi is 11 pounds.
