Question

4. В первом ряду кустов смородины в 1,5 раза больше чем во втором. Если с первого ряда пересадить 12 кустов на второй, то количество кустов смородины в каждом ряду станет одинаковым. Сколько кустов смородины было во втором ряду первоначально? помогите ​

Answer 1

Ответ:

За Х возьмем второй ряд

1,5Х-первый ряд

1,5Х-12 это сколько стало кустов в первом ряду после того как пересадили 12 кустов.

Х+12 это сколько стало кустов во втором ряду после пересадки.

1,5Х-12=Х+12

0,5Х=24

Х=48

Пошаговое объяснение:

1,5х-12-х=12

1,5х-х=12+12

0,5х=24

х=48

Answer 2

Problem Analysis

We are given that there are 1.5 times more currant bushes in the first row than in the second row. If we transplant 12 bushes from the first row to the second row, the number of currant bushes in each row will be the same. We need to determine the initial number of currant bushes in the second row.

Solution

Let's assume that the initial number of currant bushes in the second row is x. Since there are 1.5 times more currant bushes in the first row, the initial number of currant bushes in the first row would be 1.5x.

When we transplant 12 bushes from the first row to the second row, the number of currant bushes in each row becomes equal. This means that the number of bushes in the first row is reduced by 12, resulting in 1.5x - 12 bushes. The number of bushes in the second row is increased by 12, resulting in x + 12 bushes.

Since the number of bushes in each row is now the same, we can set up the equation:

1.5x - 12 = x + 12

Simplifying the equation:

0.5x = 24

Solving for x:

x = 48

Therefore, the initial number of currant bushes in the second row was 48.

Answer

The initial number of currant bushes in the second row was 48.
