Question

На первом складе 7.6 т угля меньше, чем на втором, а на двух складах вместе 100 т угля.Сколько тонн на втором складе? Срочно...

Answer 1

1склад-х
2склад-х+7.6


х+х+7.6=100
2х+7.6=100
2х=100-7.6
2х=92.4
х=92.4:2
х=46.2
1)46.2+7.6=53.8

Answer 2

Пусть на втором складе будет х т угля, тогда на первом  (х - 7.6) т угля.Вместе 100 т угля. Имеем уравнение: х+ х-7.6=100; 2х=100 - 7.6; 2х=92.4; х=92.4 :2;х=46.2(т)- на втором складе

Answer 3

Calculating the Coal Distribution

To solve this problem, we can use a system of linear equations. Let's denote the amount of coal on the first warehouse as x tons and the amount on the second warehouse as y tons. We have the following information:

1. The amount of coal on the first warehouse is 7.6 tons less than the amount on the second warehouse: x = y - 7.6. 2. The total amount of coal on both warehouses is 100 tons: x + y = 100.

Solving the System of Equations

We can solve this system of equations to find the amount of coal on the second warehouse.

Substitute the value of x from the first equation into the second equation: y - 7.6 + y = 100.

Combine like terms: 2y - 7.6 = 100.

Add 7.6 to both sides: 2y = 107.6.

Divide by 2: y = 53.8.

Answer

The amount of coal on the second warehouse is 53.8 tons.
