Question

У двох однакових мiшках зерна на 4ц20кг менше,нiж у семи таких самих мiшках. Скiльки всього зерна у цих мiшках?

Answer 1

1 мешок - x
1ц=100кг
составляем уравнение
2х+420=7х
5ч=420
х=84кг
2х=168кг
ответ:168кг

Answer 2

Solution:

To solve this problem, we can set up a system of equations based on the given information and then solve for the total amount of grain in the bags.

Let's denote: - x as the amount of grain in one bag - y as the total amount of grain in two bags - z as the total amount of grain in seven bags

We are given the following information: 1. The difference in the amount of grain between two bags and seven bags is 4c20kg.

We can express this information in the form of an equation: - 2x - 7x = 4c20kg

Now, let's solve for the total amount of grain in the bags.

Calculation:

Given the difference in the amount of grain between two bags and seven bags is 4c20kg, we can solve for the total amount of grain in the bags using the equation:

2x - 7x = 4c20kg

Solving for x: - -5x = 4c20kg - x = -4c20kg / -5 - x = -84kg

Now, we can find the total amount of grain in two bags (y) and seven bags (z): - y = 2x = 2 * (-84kg) = -168kg - z = 7x = 7 * (-84kg) = -588kg

Answer:

So, the total amount of grain in two bags is -168kg and the total amount of grain in seven bags is -588kg.
