Question

Школьники отправились на экскурсию. Их разместили в 5 автобусах и 3 вагонах.В каждом вагоне оказалось x школьников, а в каждом августе - на 17 меньше. Сколько школьников отправилось на экскурсию?

Answer 1

3x - школьников в  вагонах;
(х-17)*5=5х-85 - школьников в автобусах;
3х+5х-85=8х-85 - школьников всего.
Ответ: 8х-85 школьников.

Answer 2

Calculating the Number of Students on the Excursion

To calculate the number of students who went on the excursion, we can use the information provided about the number of buses and train cars, as well as the number of students in each train car and the reduction in the number of students in each bus.

Let's denote: - x as the number of students in each train car. - y as the number of students in each bus.

Calculating the Number of Students in the Train Cars

From the given information, we know that there were 3 train cars, and in each car, there were x students.

Calculating the Number of Students in the Buses

There were 5 buses, and in each bus, there were y students, with 17 fewer students in each subsequent bus.

Formulating the Equations

We can use the given information to form two equations: 1. Equation for the number of students in the train cars: 3x 2. Equation for the number of students in the buses: y + (y - 17) + (y - 17*2) + (y - 17*3) + (y - 17*4)

Solving for the Number of Students

By solving the equations, we can find the values of x and y, and then calculate the total number of students who went on the excursion.

Let's proceed with the calculations.
