Question

На мельницу привезли 58мешков пшеницы и 38мешков ржи. Пшеницы привезли на 8ц больше чем ржи. Сколько отдельно кг ржи и пшеницы если если масса всех мешков одинакова. :'( ЭТО 4КЛАСС Я ПРОСТО НЕ МОГУ РЕШИТЬ ЛЮДИ ПОМОГИТЕ УМНИКИ КТО ТО ТАМ ЕЩЕ ВЫ МНЕ НУЖНЫ!!!!

Answer 1

1)58-38=20 (м)-разница в мешках.
Значит в 20 мешках 8 ц =800 кг пшеницы

2)800:20=40 (кг)-вес одного мешка

3)40*58=2320 (кг)-вес пшеницы

4)40*38=1520 (кг)-вес ржи 

Answer 2

Problem Analysis

To solve this problem, we need to find the separate weights of wheat and rye given that 58 bags of wheat and 38 bags of rye were delivered to the mill. We also know that the weight of wheat is 8 tons more than the weight of rye, and the total weight of all the bags is the same.

Solution

Let's assume the weight of one bag of wheat is x kg and the weight of one bag of rye is y kg.

1. We know that 58 bags of wheat were delivered, so the total weight of wheat is 58x kg. 2. We also know that 38 bags of rye were delivered, so the total weight of rye is 38y kg. 3. The weight of wheat is 8 tons (8000 kg) more than the weight of rye, so we can write the equation: 58x = 38y + 8000.

To solve this equation, we can use the method of substitution or elimination.

Let's use the method of substitution:

From equation 3, we can rearrange it to solve for x: 58x = 38y + 8000 => x = (38y + 8000) / 58

Now we can substitute this value of x into equation 1 to find the value of y:

58x = 58((38y + 8000) / 58) => 58x = 38y + 8000

Simplifying the equation: 20x = 38y => x = (38y) / 20

Now we have two equations: x = (38y + 8000) / 58 x = (38y) / 20

We can equate these two equations to find the value of y:

(38y + 8000) / 58 = (38y) / 20

Simplifying the equation: 20(38y + 8000) = 58(38y) 760y + 160000 = 2204y

Rearranging the equation: 2204y - 760y = 160000 1444y = 160000 y = 160000 / 1444 y ≈ 110.92 kg

Now we can substitute the value of y back into one of the equations to find the value of x:

x = (38y + 8000) / 58 x = (38 * 110.92 + 8000) / 58 x ≈ 160.69 kg

Answer

Therefore, the weight of rye is approximately 110.92 kg, and the weight of wheat is approximately 160.69 kg.
