Answer 1

1) 3*5=15 кг масса трех гирь
2) 15-2=13 кг весит мешок с крупой

Answer 2

3*5=15 кг (масса 3 гирей по 5 кг)                                                                                 15-2=13 кг весит мешок с крупой                                                                                

Answer 3

Problem Setup

To find the mass of the bag of groats, we have a scenario where a bag of groats and a 2 kg weight are on one side of the scale, and on the other side, there are three weights of 5 kg each to balance the scale.

Solution

Let's calculate the mass of the bag of groats step by step.

1. First, we need to find the total weight on the side with the 2 kg weight and the bag of groats. - The total weight on one side of the scale is 2 kg (weight) + x (mass of the bag of groats).

2. Then, we need to find the total weight on the other side of the scale to balance it. - The total weight on the other side of the scale is 3 (number of weights) * 5 kg (weight of each weight).

3. Now, we can set up an equation to find the mass of the bag of groats. - The total weight on one side of the scale must be equal to the total weight on the other side of the scale for it to balance.

Calculation

Let's solve the equation to find the mass of the bag of groats.

1. Total weight on one side of the scale: 2 kg + x 2. Total weight on the other side of the scale: 3 * 5 kg = 15 kg

Setting up the equation: 2 kg + x = 15 kg

Solving for x (mass of the bag of groats): x = 15 kg - 2 kg x = 13 kg

So, the mass of the bag of groats is 13 kg.
