Question

На правой чаше весов находится груз,масса которого в 4раза меньше груза,находящегося на левой чаше весов. Если на правую чашу поставить гири в 9кг,а на левую гирь в 3кг. То весы будут в равновесии. Какова масса груза,находящегося на левой чаше весов?

Answer 1

не левой чаше висов находится гуз весом

8 кг

 

Answer 2

Вес груза в правой чашке - х, тогда в левой чашке 4х. Составим уравнение:

х+9=4х+3

4х-х=9-3

3х=6

х=2 кг - вес груза в правой чашке 

2*4=8 кг - вес груза в левой чашке 

Answer 3

Calculation of the Mass of the Load on the Left Scale

To determine the mass of the load on the left scale, we can use the information provided in the question. Let's break down the given information:

- The mass of the load on the right scale is 4 times smaller than the mass of the load on the left scale. - When 9 kg of weights are added to the right scale and 3 kg of weights are added to the left scale, the scales are in balance.

Let's assume the mass of the load on the left scale is x kg. According to the given information, the mass of the load on the right scale is 4x kg.

When 9 kg of weights are added to the right scale and 3 kg of weights are added to the left scale, the scales are in balance. This means that the total mass on both scales is equal. Mathematically, we can express this as:

4x + 9 kg = x + 3 kg

To solve this equation, we can subtract x from both sides:

4x - x + 9 kg = 3 kg

Simplifying the equation, we have:

3x + 9 kg = 3 kg

Next, we can subtract 9 kg from both sides:

3x = 3 kg - 9 kg

Simplifying further, we get:

3x = -6 kg

Finally, we can divide both sides of the equation by 3 to solve for x:

x = -6 kg / 3

Therefore, the mass of the load on the left scale is -2 kg.

Please note that the negative mass value obtained here may indicate an error or inconsistency in the given information or calculations. It is not physically possible to have a negative mass.
