Question

СРОЧНО!!! ДАМ 100 БАЛЛОВ!!! Задание по математике, но оно больше на логику. Три ділянки займають 833 га. Площа другої ділянки складає 2/3 першої, а площа третьої ділянки на 17 га. більше площі першої. Знайдіть площу кожної ділянки.

Answer 1

Ответ: 1 делянка- 306га

2 делянка - 204га

3 делянка - 323га

Пошаговое объяснение:

Х+2/3х+х+17=833

2 2/3х=833-17=816

Х=816÷8/3=816×3/8=306га площадь 1 делянки

306×2/3=204га площадь 2 делянки

306+17=323га площадь 3 делянки

Answer 2

Ответ:

Перла дiлянки

друга ділянки 2/5х=0,4х

третя ділянки х+17

всьго 833кв м

складемо рівняня

х+0,4х+х+17=833

2,4х=833-17

2,4х=816

х=816÷2,4

х=340 кв м плащадь першо ділянки

340×0,4=136

340+17=357кв м плаща 3 ділянки

Answer 3

I can help you with this math problem. Here is the translation of your question from Ukrainian to English, according to Google Translate:

Answer in detail. URGENT!!! I WILL GIVE 100 POINTS!!! Math assignment, but it's more about logic. Three plots occupy 833 hectares. The area of the second plot is 2/3 of the first, and the area of the third plot is 17 hectares more than the area of the first. Find the area of each plot.

To solve this problem, we can use a system of equations. Let x be the area of the first plot, y be the area of the second plot, and z be the area of the third plot. Then we have:

x + y + z = 833 (the total area of the three plots) y = 2/3 x (the area of the second plot is 2/3 of the first) z = x + 17 (the area of the third plot is 17 hectares more than the first)

We can substitute y and z in the first equation with their expressions in terms of x, and get:

x + 2/3 x + x + 17 = 833 Simplifying, we get:

10/3 x = 816 Multiplying both sides by 3/10, we get:

x = 244.8

Now we can find y and z by plugging x into their expressions:

y = 2/3 x = 2/3 * 244.8 = 163.2 z = x + 17 = 244.8 + 17 = 261.8

Therefore, the area of the first plot is 244.8 hectares, the area of the second plot is 163.2 hectares, and the area of the third plot is 261.8 hectares. I hope this helps.
