Question

Решите задачу СРОЧНО!!!!!!!!!!!!!! вдоль двух улиц посадили деревья для озелинения. Количество деревьев на первой улице в 1,4 раза больше , чем на второй. Когда с первой улицы пересадили 13 деревьев на вторую, то количество деревьев на обеих улицах стало равным.Сколько деревьев было посажено на каждой улице первоначально

Answer 1

Х деревьев на 2 ул., на 1 - 1.4х
1.4х-13=х+13
1.4х-х=26
0.4х=26
х=26/0.4
х=65 на 2 улице
65•1.4=91 на первой

Answer 2

Task Solution: Street Tree Planting

To solve this problem, we can use a system of equations to represent the given information and then solve for the unknowns.

Let's denote: - x as the number of trees on the second street. - 1.4x as the number of trees on the first street initially. - After transplanting 13 trees from the first street to the second, the number of trees on both streets becomes equal.

We can represent this information in the following equations:

1. 1.4x - 13 = x 2. 1.4x = x + 13

Let's solve these equations to find the initial number of trees on each street.

Solution:

1. 1.4x - 13 = x - Subtract x from both sides: 0.4x - 13 = 0 - Add 13 to both sides: 0.4x = 13 - Multiply by 10 to clear the decimal: 4x = 130 - Divide by 4: x = 32.5

2. 1.4x = x + 13 - Substitute the value of x from the first equation: 1.4(32.5) = 32.5 + 13 - 45.5 = 45.5

Answer:

The initial number of trees on the first street was 45 and on the second street was 32.
