Question

пшеницей, рожью и ячменем засеяно 8400га пашни. Рожью было засеяно в 5 раз больше, чем ячменем, а пшеницей столько,сколько ячменем и рожью вместе. Сколько гектаров засеяно каждой культурой?

Answer 1

х- засеяно ячменем

5х- засеяно рожью

х+5х- засеяно пшеницей

х+5х+(х+5х)=8400

12х=8400

х=8400/12

х= 700

 700га- засеяно ячменем
5*700=3500га - засеяно рожью
700+5*700=4200- засеяно пшеницей

 

Answer 2

Calculation of Cultivated Area for Wheat, Rye, and Barley

To determine the number of hectares sown with each crop, we can use the information provided. Let's break down the given information step by step:

1. The total cultivated area is 8,400 hectares, which includes wheat, rye, and barley. 2. The area sown with rye is five times greater than the area sown with barley. 3. The area sown with wheat is equal to the combined area sown with rye and barley.

Now, let's calculate the area sown with each crop:

1. Let's assume the area sown with barley is x hectares. 2. The area sown with rye is five times greater than the area sown with barley, so it would be 5x hectares. 3. The area sown with wheat is equal to the combined area sown with rye and barley, which is x + 5x = 6x hectares.

We know that the total cultivated area is 8,400 hectares, so we can set up the following equation:

x + 5x + 6x = 8,400

Simplifying the equation:

12x = 8,400

Dividing both sides by 12:

x = 700

Therefore, the area sown with barley is 700 hectares, the area sown with rye is 5 * 700 = 3,500 hectares, and the area sown with wheat is 6 * 700 = 4,200 hectares.

Summary:

Based on the given information, the area sown with each crop is as follows: - Barley: 700 hectares - Rye: 3,500 hectares - Wheat: 4,200 hectares
