Question

На одной машине привезли 120 кирпичей а на второй 154 таких же кирпича Масса кирпичей в первой машине на 136 кг меньше массы кирпичей во второй машине Найди массу кирпичей в каждой машине

Answer 1

Легко
1) 154-120=34(кир)
2) 136:34=4(кг)-вес одного керпича.
3) 4*154=616(кг)
4) 4*120=480(кг)
Ответ: 616 кг,480 кг.
вот и все

Answer 2

154-120=34 (на 34 кирпичей больше во 2 машине)                                                 136:34=4 кг весит один кирпич                                                                                 120*4=480 кг масса кирпичей в 1 машине                                                                 154*4=616 кг масса кирпичей во 2 машине

Answer 3

Problem Analysis

We are given two cars, one carrying 120 bricks and the other carrying 154 bricks. The mass of the bricks in the first car is 136 kg less than the mass of the bricks in the second car. We need to find the mass of the bricks in each car.

Solution

Let's assume the mass of the bricks in the first car is x kg. According to the problem, the mass of the bricks in the second car is x + 136 kg.

We can set up the following equation based on the given information:

x + (x + 136) = total mass of bricks in both cars

Simplifying the equation, we get:

2x + 136 = total mass of bricks in both cars

Now, let's substitute the number of bricks in each car into the equation. The first car has 120 bricks, and the second car has 154 bricks.

2x + 136 = (mass of each brick in the first car) * (number of bricks in the first car) + (mass of each brick in the second car) * (number of bricks in the second car)

2x + 136 = (mass of each brick) * (120) + (mass of each brick) * (154)

Simplifying further, we get:

2x + 136 = (mass of each brick) * (120 + 154)

Now, we can solve this equation to find the mass of each brick.

Calculation

Let's calculate the mass of each brick using the given information.

The first car has 120 bricks, and the second car has 154 bricks.

Using the equation 2x + 136 = (mass of each brick) * (120 + 154), we can substitute the values:

2x + 136 = (mass of each brick) * (274)

Now, we can solve for x:

2x = (mass of each brick) * (274) - 136

x = [(mass of each brick) * (274) - 136] / 2

Answer

The mass of the bricks in the first car, with 120 bricks, is [(mass of each brick) * (274) - 136] / 2 kg.

The mass of the bricks in the second car, with 154 bricks, is [(mass of each brick) * (274) + 136] / 2 kg.

Please note that we need the mass of each brick to calculate the exact values. Unfortunately, the search results did not provide the specific mass of each brick.
