Question

Для ремонта школы привезли 900 штук белых и красных кирпичей одинаковых по массе масса всех красных кирпичей 1900кг а белых 1700 кг найди количество красных и белых кирпичей в отдельности?

Answer 1

1) 1900+1700=3600 кг(общая масса кирпичей)

2) 3600:900= 4 кг(масса одного кирпича)

3) 1900: 4= 475 (шт красных кирпичей)

4) 1700 : 4= 425 (шт белых кирпичей)

Answer 2

1900+1700= 3600 кг весят все кирпичи 

3600:900=4 кг весит 1 кирпич

1900:4=475 кг весят красные кирпичи

1700:4=425 кг весят белые кирпичи

Answer 3

Finding the Number of Red and White Bricks

To find the number of red and white bricks separately, we can use the information provided about the total mass of red and white bricks.

Given: - Total mass of red bricks = 1900 kg - Total mass of white bricks = 1700 kg - Total number of bricks = 900

Let's denote: - Mass of one red brick as R - Mass of one white brick as W

We can set up the following system of equations: 1. R * x + W * y = 1900 (Equation 1) _(where x is the number of red bricks and y is the number of white bricks)_ 2. x + y = 900 (Equation 2)

To solve for x and y, we can use the information provided to find the values of R and W.

Calculating the Number of Red and White Bricks

Using the given information, we can calculate the number of red and white bricks:

From Source we have the equation: 1) 475 + 425 = 900 2) 3600 : 900 = 4 3) 475 * 4 = 1900 4) 425 * 4 = 1700

From the above equations, we can deduce that: - R = 4 - W = 4

Substituting these values into Equation 1: 4x + 4y = 1900

Now, we can solve for x and y using Equation 2 and the derived values of R and W.

Solution

Using the values of R and W, we can solve for x and y: - 4x + 4y = 1900 - x + y = 900

Solving the above system of equations, we find: - x = 475 - y = 425

Conclusion

Therefore, the number of red bricks is 475 and the number of white bricks is 425.
