Question

3 корпусах дома живут 865 человек сколько жильцов в каждом корпусе если в первом и третьем корпусах живут 508 человек а во втором и третьем 475человек

Answer 1

865-508=357(ч)-во втором подъезде
475-357=118(ч)-в третьем
865-475=390(ч)-в первом

Answer 2

865-508=357(жил.)-2 подъезд
457-357=100(жил.)-3 подъезд
865-475=420(жил.) 1 подъезд

Answer 3

Calculating the Number of Tenants in Each Building

To calculate the number of tenants in each building, we can use the information provided in the search results.

Given: - Total number of tenants in all three buildings: 865 - Number of tenants in the first and third buildings: 508 - Number of tenants in the second and third buildings: 475

Let's denote the number of tenants in the first building as x, the number of tenants in the second building as y, and the number of tenants in the third building as z.

We can set up the following system of equations based on the given information: 1. x + z = 508 (Equation 1) 2. y + z = 475 (Equation 2) 3. x + y + z = 865 (Equation 3)

We can solve this system of equations to find the values of x, y, and z.

Solving the System of Equations

Substituting the values of z from Equation 1 and Equation 2 into Equation 3, we get: x + (508 - x) + (475 - (508 - x)) = 865 x + 508 - x + 475 - 508 + x = 865 x - x + x + 475 - 508 + 508 = 865 x + 475 = 865 x = 865 - 475 x = 390

Now that we have the value of x, we can find the value of y: y + 508 = 865 y = 865 - 508 y = 357

Finally, we can find the value of z: z = 508 - x z = 508 - 390 z = 118

Conclusion

Based on the given information, the number of tenants in each building is as follows: - First building: 390 tenants - Second building: 357 tenants - Third building: 118 tenants
