Question

Для ремонта школы привезли 475 штук одинаковых по массе красных кирпичей и 425 штук таких же по массе белых кирпичей масса всех кирпичей 3600 кг найди массу красных и белых кирпичей в отдельности

Answer 1

425 + 425 = 900 - всего кирпичей
Найдем массу одного кирпича:
3600:900 = 4 кг.
Масса белых кирпичей равна 425*4=1700
Масса красных кирпичей равна 475*4=1900 или 3600-1700=1900

Answer 2

475+425=900 всех кирпичей
3600:900=4 масса 1 кирпича
4*475=1900 красный кирпичей
4*425=1700 белый кирпичей

Answer 3

Calculation of the Mass of Red and White Bricks

To find the mass of the red and white bricks separately, we need to set up a system of equations based on the information given.

Let's assume the mass of each red brick is x kg, and the mass of each white brick is y kg.

According to the problem, there are 475 red bricks and 425 white bricks, and the total mass of all the bricks is 3600 kg.

We can set up the following equations:

1. Equation 1: 475x + 425y = 3600 (since the total mass of all the bricks is 3600 kg) 2. Equation 2: x = y (since the red and white bricks have the same mass)

To solve this system of equations, we can substitute Equation 2 into Equation 1:

475x + 425x = 3600

Simplifying the equation:

900x = 3600

Dividing both sides by 900:

x = 4

Since x = y, the mass of each red and white brick is 4 kg.

Therefore, the mass of the red bricks is 475 * 4 = 1900 kg, and the mass of the white bricks is 425 * 4 = 1700 kg.

So, the mass of the red bricks is 1900 kg, and the mass of the white bricks is 1700 kg.
