Question

В фермерском хозяйстве 3\5 поля засеяли пшеницей,а 7/20 поля-овощами. S поля,засеянного пшеницей,на 17 га больше,чем S занятая овощами. Вся площадь-? Ответ известен,нужно решение!!!

Answer 1

Пусть х - будет вся площадь. Тогда часть с пшеном будет равна 3/5х. А овощи 7/20х. А разница будет 17. Получаем уравнение :
3/5x-7/20x=17 
0.6x-0.35x=17
0.25x=17   /0.25
x=68

а х у нас и было всей площадью поля)) 

Answer 2

Problem Analysis

We are given that 3/5 of a farm field is planted with wheat and 7/20 of the field is planted with vegetables. The area of the field planted with wheat is 17 hectares larger than the area planted with vegetables. We need to find the total area of the field.

Solution

Let's assume the total area of the field is x hectares.

According to the given information: - 3/5 of the field is planted with wheat, which is equal to (3/5) * x hectares. - 7/20 of the field is planted with vegetables, which is equal to (7/20) * x hectares.

We are also given that the area planted with wheat is 17 hectares larger than the area planted with vegetables. So we can write the equation:

(3/5) * x = (7/20) * x + 17

To solve this equation, we can start by simplifying it:

(3/5) * x - (7/20) * x = 17

Now, let's find a common denominator for the fractions:

(12/20) * x - (7/20) * x = 17

Combining the terms with x:

(12/20 - 7/20) * x = 17

Simplifying further:

(5/20) * x = 17

Now, let's solve for x:

x = (17 * 20) / 5

Evaluating the expression:

x = 68 hectares

Therefore, the total area of the field is 68 hectares.

Answer

The total area of the field is 68 hectares.
