Question

Кустов малины в первом ряду в 1.5 раза больше,чем кустов малины во втором ряду.после того как с первого ряда пересадили на второй 4 куста, в обоих рядах стало поровну.Сколько кустов малины во втором ряду было первоначально?

Answer 1

Х - кол-во кустов во втором ряду
тогда
х*1.5 - кол-во кустов в первом ряду

4 куста убрали с первого ряда, получаем 1.5х-4
4 куста прибавили на второй ряд, получаем х+4
и в рядах кустов стало поровну, т.е. получаем уравнение:

1.5х-4=х+4
1.5х-х=4+4
0.5х=8
х=8:0.5
х=16 (к) во втором ряду было первоначально

х*1.5 в первом ряду
16*1.5=24 (к) в первом ряду было первоначально

1.5*16-4=16+4
20=20 (к) стало в каждом ряду после пересадки

Answer 2

Problem Analysis

We are given that the number of raspberry bushes in the first row is 1.5 times greater than the number of bushes in the second row. After transplanting 4 bushes from the first row to the second row, the number of bushes becomes equal in both rows. We need to determine the initial number of raspberry bushes in the second row.

Solution

Let's assume the initial number of raspberry bushes in the second row is x. According to the given information, the number of bushes in the first row is 1.5 times greater than the number in the second row. Therefore, the number of bushes in the first row is 1.5x.

After transplanting 4 bushes from the first row to the second row, the number of bushes becomes equal in both rows. This means that the number of bushes in the first row is now 1.5x - 4, and the number of bushes in the second row is now x + 4.

Since the number of bushes is now equal in both rows, we can set up the following equation:

1.5x - 4 = x + 4

Simplifying the equation, we get:

0.5x = 8

Dividing both sides of the equation by 0.5, we find:

x = 16

Therefore, the initial number of raspberry bushes in the second row was 16.

Answer

The initial number of raspberry bushes in the second row was 16.
