Question

Даю 20 баллов Помогите решить задачу: В первом ряду кустов смородины в 2,5 раза больше, чем во втором. Если с первого ряда пересадить 12 кустов на второй, то кол-во кустов смородины в каждом ряду станет одинаковым. Сколько кустов смородины было во втором ряду первоначально?)

Answer 1

Во 2 ряду кустов - х шт
в 1 ряду - 2,5х
после пересадки в 1 ряду осталось (2,5х-12)
х=2,5х-12
2,5х-х=12
1,5х=12
х=12/1,5
х=8 кустов смородины было первоначально во 2 ряду

Answer 2

В первом ряду 2,5х-12
второй ряд   х+12

2,5х-12=х+12
2,5х-х=12+12
1,5х=24
х=24:1,5=16 второй ряд.      2,5*16=40 кустов первый ряд
                              

Answer 3

Problem Analysis

To solve this problem, we need to determine the initial number of currant bushes in the second row. We are given that the number of currant bushes in the first row is 2.5 times greater than the number in the second row. Additionally, if 12 bushes are transferred from the first row to the second row, the number of bushes in each row becomes equal.

Solution

Let's assume that the initial number of currant bushes in the second row is x. According to the problem statement, the number of currant bushes in the first row is 2.5 times greater than the number in the second row. Therefore, the number of currant bushes in the first row is 2.5x.

If 12 bushes are transferred from the first row to the second row, the number of bushes in each row becomes equal. This means that the number of currant bushes in the first row is now 2.5x - 12, and the number of currant bushes in the second row is x + 12.

To find the initial number of currant bushes in the second row, we can set up the following equation:

x + 12 = 2.5x - 12

Simplifying the equation:

2x = 24

x = 12

Therefore, the initial number of currant bushes in the second row was 12.

Answer

The initial number of currant bushes in the second row was 12.
