Question

В пробке стоят 750 автомобилей. Автобусы имеют по 6 колес, а легковые по 4 колеса. Всего колес 3024. Сколько автобусов и легковых атомобилей стоит в пробке?

Answer 1

6x+4(750-x)=3024
6x+3000-4x=3024
2x+3000=3024
2x=3024-3000
2x=24
x=24:2
х=12 автоб
750-х=750-12=738 м

Answer 2

Calculating the Number of Vehicles in the Traffic Jam

To calculate the number of buses and cars in the traffic jam, we can use the given information about the total number of vehicles and the total number of wheels.

Given: - Total number of vehicles in the traffic jam = 750 - Buses have 6 wheels each - Cars have 4 wheels each - Total number of wheels = 3024

Let's denote: - Number of buses as B - Number of cars as C

We can form the following equations based on the given information: 1. B + C = 750 (Total number of vehicles) 2. 6B + 4C = 3024 (Total number of wheels)

Solving the Equations

We can solve the above system of equations to find the values of B (number of buses) and C (number of cars).

First, let's solve the equation B + C = 750 for B: B = 750 - C

Substitute B = 750 - C into the second equation: 6(750 - C) + 4C = 3024 4500 - 6C + 4C = 3024 4500 - 2C = 3024 -2C = 3024 - 4500 -2C = -1476 C = -1476 / -2 C = 738

Now that we have found the value of C, we can find the value of B: B = 750 - 738 B = 12

Answer:

There are 12 buses and 738 cars in the traffic jam.
