Answer 1

5*2=10 столов помыли мальчики
7*2=14 столов помыли девочки
Всего столов:
14+10=24

Answer 2

Calculating the Total Number of Tables in the Classroom

To calculate the total number of tables in the classroom, we can use the information provided in the question and the fact that each child washed an equal number of tables, with the girls washing 4 more tables than the boys.

Let's denote: - B as the number of tables washed by each boy - G as the number of tables washed by each girl

We know that there were 5 boys and 7 girls, and each child washed an equal number of tables. Additionally, the girls washed 4 more tables than the boys.

We can set up the following equations: 1. 5B = 7G (each boy washed an equal number of tables as each girl) 2. G = B + 4 (the girls washed 4 more tables than the boys)

We can solve this system of equations to find the values of B and G, and then calculate the total number of tables in the classroom.

Solving the Equations

Let's solve the system of equations: 1. 5B = 7G 2. G = B + 4

Substitute the value of G from equation 2 into equation 1: 5B = 7(B + 4)

Expand and solve for B: 5B = 7B + 28 -2B = 28 B = -14

This result doesn't make sense, so let's re-evaluate the problem.

Re-evaluating the Problem

It seems there might be a mistake in the initial setup of the problem. Let's reconsider the information provided and try to solve the problem again.

Given: - 5 boys and 7 girls - Each child washed an equal number of tables - The girls washed 4 more tables than the boys

Let's denote: - T as the total number of tables in the classroom - x as the number of tables washed by each child

We can set up the following equations: 1. 5x = 7(x + 4) (each boy washed an equal number of tables as each girl, and the girls washed 4 more tables than the boys) 2. T = 5x (the total number of tables is equal to 5 times the number washed by each child)

Calculating the Total Number of Tables

Let's solve the equation 5x = 7(x + 4) to find the value of x, and then calculate the total number of tables in the classroom.

5x = 7x + 28 -2x = 28 x = -14

This result also doesn't make sense, so there might be an error in the initial problem statement. It's possible that the information provided may not lead to a feasible solution for the total number of tables in the classroom.
