Answer 1

1 бригада это х ц
2 бригада это х + 1,57 ц                                         Вместе 20,4 ц
Решение.
Надо 20,4 - 1,57=18,83
И 18,83 мы делим на 2
Ответ мы нашли первую бригада
Теперь вторую мы просто. ответ + 1,57 = вторая бригада.
Потом в ответе запишешь 1 бригада  и 2 бригада.

Answer 2

Problem Analysis

We are given that two teams of cotton pickers collected a total of 20.4 centners (ц) of cotton in a day. The first team collected 1.57 centners more than the second team. We need to determine how much cotton each team collected.

Solution

Let's assume that the second team collected x centners of cotton. Since the first team collected 1.57 centners more than the second team, the first team must have collected (x + 1.57) centners of cotton.

According to the given information, the total amount of cotton collected by both teams is 20.4 centners. We can write this as an equation:

x + (x + 1.57) = 20.4

Simplifying the equation:

2x + 1.57 = 20.4

Subtracting 1.57 from both sides:

2x = 18.83

Dividing both sides by 2:

x = 9.415

Therefore, the second team collected 9.415 centners of cotton, and the first team collected (9.415 + 1.57) = 10.985 centners of cotton.

Answer

The second team collected approximately 9.415 centners of cotton, while the first team collected approximately 10.985 centners of cotton.
