Question

Вдоль двух улиц посадили деревья для озеленения.Количество деревьев на1 улице в 1,4 раза больше, чем на второй.Когда с первой улицы пересадили 34 дерева на вторую то количество деревьев на обеих улицах стало равным.Сколько деревьев было посажено на каждой улице?​

Answer 1

1,4x-34=x+34, где x - кол-во деревьев на второй улице;

1,4x-x=34+34

0,4x=68

x=68÷0,4

x=170 деревьев было посажено на 2-й улице;

1,4x=1,4×170=238 деревьев было посажено на 1-й улице.

Answer 2

Problem Analysis

We are given two streets where trees were planted for landscaping purposes. The number of trees on the first street is 1.4 times greater than the number of trees on the second street. When 34 trees were transferred from the first street to the second street, the number of trees on both streets became equal. We need to determine the number of trees that were planted on each street.

Solution

Let's assume the number of trees on the second street is x. Then, the number of trees on the first street would be 1.4x, as stated in the problem.

When 34 trees were transferred from the first street to the second street, the number of trees on both streets became equal. This means that the number of trees on the first street decreased by 34, while the number of trees on the second street increased by 34.

Based on this information, we can set up the following equation:

1.4x - 34 = x

Now, let's solve this equation to find the value of x, which represents the number of trees on the second street.

1.4x - x = 34 0.4x = 34 x = 34 / 0.4 x = 85

Therefore, the number of trees on the second street is 85.

To find the number of trees on the first street, we can substitute the value of x into the equation:

1.4x = 1.4 * 85 = 119

Therefore, the number of trees on the first street is 119.

Answer

There were 119 trees planted on the first street and 85 trees planted on the second street.
