Answer: The cat's weight is 4.33 pounds
• The dog's weight is 17.32 pounds.
Step-by-step explanation:
Let the weight of the cat be represented by a.
Devi’s dog weighs 4 times as much as her cat. This can be written as:
= 4 × a
= 4a
Her dog also weighs 13 pounds more than the cat. This can be written as:
= a + 13
We then equate both equations. This will be:
4a = a + 13
4a - a = 13
3a = 13
a = 13/3
a = 4.33 pounds
The cats weight is 4.33 pounds
Since the dog's weight = 4a = 4 × 4.33 = 17.32 pounds
