Answer 1

Задача 1
18-12=6(б)-больше в 1-м магазине
228:6=38(л)-в одном бидоне
18х38=684(л)-в 1-м магазине
12х38=456(л)-во 2-м магазине
Задача 2
684-456=228(л)-в 6 бидонах
228:6=38(л)-в одном бидоне
684:38=18(б)-в 1-м магазине
456:38=12(б)-во 2-м магазине.

Answer 2

Task 1: В один магазин привезли 18 одинаковых бидонов молока, а в другой 12 таких же. В первый магазин привезли на 228 л молока больше, чем во второй. Сколько литров молока привезли в каждый магазин?

To solve this problem, we can set up a system of equations. Let's assume that the amount of milk in the first store is represented by variable x, and the amount of milk in the second store is represented by variable y.

From the given information, we know that: - The first store received 18 identical milk containers, and the second store received 12 identical milk containers. - The first store received 228 liters more milk than the second store.

Based on these facts, we can set up the following equations:

Equation 1: x = 18 * y (since the first store received 18 identical containers) Equation 2: x = y + 228 (since the first store received 228 liters more than the second store)

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

18 * y = y + 228

Now, let's solve for y:

18y - y = 228 17y = 228 y = 228 / 17 y ≈ 13.41

Since we can't have a fraction of a container, we can round y to the nearest whole number:

y ≈ 13

Now, let's substitute the value of y back into Equation 1 to find x:

x = 18 * 13 x = 234

Therefore, approximately 234 liters of milk were delivered to the first store, and approximately 13 liters of milk were delivered to the second store.

Answer: Approximately 234 liters of milk were delivered to the first store, and approximately 13 liters of milk were delivered to the second store.

Task 2: В один магазин привезли в одинаковых бидонах 684 л молока, а в другой 456 л молока в таких же бидонах. В первый магазин на 6 бидонов молока больше, чем во второй. Сколько бидонов молока привезли в каждый магазин?

To solve this problem, we can set up a system of equations. Let's assume that the number of containers in the first store is represented by variable x, and the number of containers in the second store is represented by variable y.

From the given information, we know that: - The first store received 684 liters of milk in identical containers, and the second store received 456 liters of milk in identical containers. - The first store received 6 more containers of milk than the second store.

Based on these facts, we can set up the following equations:

Equation 1: x * y = 684 (since the first store received 684 liters of milk) Equation 2: (x - 6) * y = 456 (since
