Question

Помогите решить задачу срочно В одном заповеднике было в 5 раз больше дубов, чем в другом. Когда во втором заповеднике посадили еще 16 дубов, то дубов в заповеднике стало поровну. Сколько дубов было в каждом заповеднике первоначально?

Answer 1

Один заповедник - х дубов
Второй заповедник -5*х дубов
Уравнение: 5х-х=16   (или  х+16=5х)
5х-х=16
4х=16
х=16:4
х=4 - дуба в первом заповеднике,
4*5 = 20 - дубов во втором заповеднике

 

Answer 2

На угад: в 1 заповеднике было 20 дубов (20:5=4) во втором. 4+16=20

Answer 3

Task Solution:

Let's solve the problem step by step.

1. Set up the Equations: - Let's assume the number of oak trees in the first reserve is represented by x and the number of oak trees in the second reserve is represented by y. - According to the given information, the number of oak trees in the first reserve is 5 times more than the number in the second reserve. This can be represented as: x = 5y. - After 16 oak trees were planted in the second reserve, the number of oak trees in both reserves became equal. This can be represented as: x = y + 16.

2. Solve the Equations: - We can solve these two equations to find the values of x and y.

3. Calculation: - Substituting the value of x from the first equation into the second equation, we get: 5y = y + 16. - Solving for y: 5y - y = 16 => 4y = 16 => y = 4. - Substituting the value of y back into the first equation, we get: x = 5*4 => x = 20.

Answer:

The initial number of oak trees in the first reserve was 20, and in the second reserve was 4.
