Question

зал кінотеатру містить 500 місць, причому кожний ряд містить однакову кількість місць. кількість рядів у кінотеатрі на 5 менша за кількість місць у кожному ряду , скільки місць містить кожний ряд кінотеатру?​

Answer 1

Ответ:

20 рядов и 25 мест

Пошаговое объяснение:

методом подбора или уравнением

кол-во рядов берем за Х

кол-во мест в ряду за Х+5

Х(Х+5)=500

Х²+5Х-500=0

D=25+2000=2025=45²

X¹=(-5+45)/2=20

Х²=(-5-45)/2=-25 не подходит

а значит 20 рядов и 25 мест

Answer 2

Calculation of the Number of Seats in Each Row

To determine the number of seats in each row of the cinema theater, we need to consider the given information.

The theater contains 500 seats, and each row has the same number of seats. The number of rows in the theater is 5 less than the number of seats in each row.

Let's denote the number of seats in each row as x.

According to the given information, the equation can be set up as follows:

x * (x - 5) = 500

To solve this equation, we can use algebraic methods or trial and error. However, since we have search results available, let's use them to find the answer.

According to the search results, we have the following snippets:

- Source "2012 . 64 ... 5)." - Source "2009. . 32." - Source "192. Page 5. 2 5."

Unfortunately, none of the snippets provide the necessary information to directly answer the question. However, we can still proceed with the calculation using algebraic methods.

By solving the equation x * (x - 5) = 500, we find that x = 25.

Therefore, each row in the cinema theater contains 25 seats.
