Alis dog weighs 8 times as much as her cat. together, the two pets weigh 54 pynds. how much does alis dog weigh?

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.
