Final answer:
The freezer weighs 150 pounds.
Step-by-step explanation:
Let's denote the weight of the freezer as F. According to the information given, the fridge weighs three times as much as the freezer. So, the weight of the fridge can be represented as 3F. Together, the fridge and freezer weigh 600 pounds. This can be expressed as the equation F + 3F = 600. Simplifying, we get 4F = 600. Dividing both sides by 4, we find that F = 150. Therefore, the freezer weighs 150 pounds.
