Question

В автопарке было в 5 раз больше грузовых автомобилей,чем легковых. После тога как рейс вышло 48 грузовых и 5 легковых автомобилей,в автопарке осталось грузовых автомобилей на 9 больше,чем легковых. Сколько легковых и сколько грузовых автомобилей в автопарке.​

Answer 1

Ответ:

Принимаем за x кол-во легковых автомобилей.

5x- грузовые автомобили.

Можно составить уравнение(после выезда)

5х-48=х-5+9

5х-х=48+4

4х=52

х=52:4

х=13 легковых

5х=13*5

5х=65

x=13 грузовых

Answer 2

Problem Analysis

We are given that in an auto park, there were 5 times more trucks than cars. After 48 trucks and 5 cars left on a trip, there were 9 more trucks than cars remaining in the auto park. We need to find the number of cars and trucks in the auto park.

Solution

Let's assume the number of cars in the auto park is C and the number of trucks is T.

From the given information, we can form two equations:

1. There were 5 times more trucks than cars in the auto park: - T = 5C 2. After 48 trucks and 5 cars left on a trip, there were 9 more trucks than cars remaining in the auto park: - T - 48 = C + 5 + 9

Now, we can solve these equations to find the values of C and T.

Substituting the value of T from equation 1 into equation 2, we get:

5C - 48 = C + 5 + 9

Simplifying the equation:

4C = 52

Dividing both sides by 4:

C = 13

Substituting the value of C back into equation 1, we get:

T = 5(13) = 65

Therefore, there are 13 cars and 65 trucks in the auto park.

Answer

There are 13 cars and 65 trucks in the auto park.
