Question

На одном участке посадили 9 рядов смородины по 23 куста в каждом ряду и несколько рядов смородины по 25 кустов в ряду. Сколько было всего рядов, если посадили 307 кустов? Пожалуйста помогите напишите пояснения пожалуйста!!!!!!!

Answer 1

Посадили 9рядов по 23куста, и х рядов по 25кустов. Всего было 307 кустов. Х•25+9•23=307; 25х+207=307; 25х=100; Х=4(ряда по 25 кустов) 9+4=13рядов посадили всего

Answer 2

Было всего 17 рядов смородины.

Answer 3

Calculating the Number of Rows of Currant Bushes Planted

To calculate the total number of rows of currant bushes planted, we can use the information provided about the number of rows and bushes in each row.

Let's denote: - x as the number of rows with 23 bushes in each row - y as the number of rows with 25 bushes in each row

We are given that: - 9 rows were planted with 23 bushes in each row - Several rows were planted with 25 bushes in each row - The total number of bushes planted is 307

We can form the following equations based on the given information: 1. x + y = total number of rows 2. 23x + 25y = 307

We can solve these equations to find the values of x and y, and then calculate the total number of rows.

Solving the Equations

Let's solve the system of equations: 1. x + y = total number of rows 2. 23x + 25y = 307

Using the substitution method or any other suitable method, we can find the values of x and y.

Calculation

Let's denote: - x as the number of rows with 23 bushes in each row - y as the number of rows with 25 bushes in each row

We can solve the system of equations to find the values of x and y:

From equation 1: x = total number of rows - y

Substitute x in equation 2: 23(total number of rows - y) + 25y = 307 23*total number of rows - 23y + 25y = 307 23*total number of rows + 2y = 307 2y = 307 - 23*total number of rows y = (307 - 23*total number of rows)/2

We can use this value of y to find the corresponding value of x and then calculate the total number of rows.

Final Calculation

Using the calculated value of y, we can find the corresponding value of x: x = total number of rows - y

Then, the total number of rows will be: Total number of rows = x + y

Let's calculate the values of x, y, and the total number of rows.
