2)115-12=103 (м) легвовых
3)145+115+103=363(м) всего

Answer 2

Problem Analysis

To solve this problem, we need to determine the total number of vehicles in the garage of a transportation company. We are given the following information: - There are 145 buses in the garage, which is 30 more than the number of trucks. - The number of cars is 12 less than the number of trucks.

Solution

Let's break down the problem step by step to find the total number of vehicles in the garage.

1. Let's assume the number of trucks in the garage is x. 2. According to the given information, the number of buses is 30 more than the number of trucks. So, the number of buses is x + 30. 3. The number of cars is 12 less than the number of trucks. So, the number of cars is x - 12. 4. To find the total number of vehicles in the garage, we need to add the number of trucks, buses, and cars: x + (x + 30) + (x - 12).

Now, let's simplify the equation and find the value of x.

Calculation

To find the value of x, we can solve the equation:

x + (x + 30) + (x - 12) = 145

Simplifying the equation:

3x + 18 = 145

Subtracting 18 from both sides:

3x = 127

Dividing both sides by 3:

x = 42.33

Since the number of vehicles cannot be a fraction, we need to round down the value of x to the nearest whole number.

Therefore, the number of trucks in the garage is 42.

Answer

The total number of vehicles in the garage is the sum of the number of trucks, buses, and cars:

42 + (42 + 30) + (42 - 12) = 42 + 72 + 30 = 144

Therefore, there are a total of 144 vehicles in the garage of the transportation company.

Please note that the calculations are based on the given information and assumptions made.
