Final answer:
To find the weight of the empty truck, subtract the weight of the load from the weight of the loaded truck. The weight of the empty truck is 8,487 pounds.
Step-by-step explanation:
To find the weight of the empty truck, we can subtract the weight of the load from the weight of the loaded truck. Let's assume the weight of the empty truck is x. The equation can be written as:
Weight of loaded truck - Weight of load = Weight of empty truck.
To solve the equation, we have: 17,200 - 8,713 = x. Therefore, the weight of the empty truck is 8,487 pounds.
