Answer 1

Ответ:

19кг

Пошаговое объяснение:

1) на одну чашу положыть 12 и 13 кг

2) 12кг разложыть по двум чашкам (6на6 на каждой)

Получаешь 6кг с одной чаш и 13 отложено (всего 19кг)

Answer 2

Solving for the Weight of Nails

To solve this problem, we can use a balance scale and a set of weights to measure the weight of the nails. Let's break down the process step by step.

Step 1: Weighing 12 kg

First, we can use the balance scale and weights to measure 12 kg of nails. We'll use the weights and the balance scale to find a combination that balances the 12 kg of nails.

Step 2: Weighing 11 kg

Next, we can remove one of the 1 kg weights from the balance scale, leaving us with 11 kg of nails on one side and the weights on the other side. Again, we'll use the weights to find a combination that balances the 11 kg of nails.

Step 3: Calculating the Weight of the Nails

By following this process, we can determine the weight of the nails. We'll use the weights and the balance scale to find the combination that balances the 11 kg of nails, and this will give us the weight of the nails.

This method allows us to measure 19 kg of nails using the balance scale and a set of weights.
