Question

В первой грядке в 2,5 раза больше кустов, чем на второй. Если пересадить 12 кустов с первой на вторую, то станет поровну.Сколько было на второй грядке первоначально

Answer 1

                   1 грядка         2 грядка

------------------------------------------------

Было           2,5*х                 х

------------------------------------------------

Стало         2,5*х - 12           х+12

-----------------------------------------------

 

2,5х-12 = х+12

2,5х-х=12+12

1,5х=24

х=24:1,5

х=16(кустов)-было на второй грядке первоначально

Answer 2

х кустов - на 2-ой грядке

2,5х кустов на 2-ой грядке

2,5х-12=х+12

1,5х-х=24

х=24:1,5

х=16 кустов было первоначально на второй грядке

 

Answer 3

Problem Analysis

We are given two rows of bushes, and the first row has 2.5 times more bushes than the second row. If we move 12 bushes from the first row to the second row, the number of bushes will be equal in both rows. We need to determine the initial number of bushes in the second row.

Solution

Let's assume that the initial number of bushes in the second row is x. According to the given information, the first row has 2.5 times more bushes than the second row. Therefore, the initial number of bushes in the first row can be calculated as 2.5x.

When 12 bushes are moved from the first row to the second row, the number of bushes in both rows becomes equal. We can set up the following equation to represent this situation:

2.5x - 12 = x

Now, let's solve this equation to find the initial number of bushes in the second row.

Solving the Equation

To solve the equation, we can simplify it as follows:

2.5x - 12 = x

Subtract x from both sides:

2.5x - x - 12 = 0

Combine like terms:

1.5x - 12 = 0

Add 12 to both sides:

1.5x = 12

Divide both sides by 1.5:

x = 12 / 1.5

Simplifying the right side:

x = 8

Therefore, the initial number of bushes in the second row was 8.

Answer

The initial number of bushes in the second row was 8.
