The weight of the Alis dog is pounds.
Further explanation:
Consider the weight of the Alis dog as pounds and weight of the cat as
pounds.
Since, the weight of the Alis dog is 8 times the weight of the cat. It can be written as follows:
......(1)
Now, the total weight of the cat and dog are given as 54 pounds. It can be written as follows:
......(2)
From equation (1), substitute for
in equation (2).
Thus, the weight of the cat is 6 pounds.
Substitute 6 for in equation (1) to obtain the weight of Alis dog as follows:
Thus, the weight of the Alis dog is 48 pounds.
