Question

Три машины перевезли 40 тонн груза.Первая машина перевезла 35% груза,а вторая машина перевезла на 2 тонны больше третьей.Сколько груза перевезла каждая машина?Помогите плиз срочно!Завтра самостоялка!Плиззз!!!!=^"^=

Answer 1

Первая 14 тонн, вторая 14 тонн, третья 12 тонн 40000 - 35%= 14000 40000-14000= 26000 26000-2000= 24000 24000/2= 12000

Answer 2

Problem Analysis

We are given that three cars transported a total of 40 tons of cargo. The first car transported 35% of the cargo, and the second car transported 2 tons more than the third car. We need to determine how much cargo each car transported.

Solution

Let's solve the problem step by step:

1. Calculate the amount of cargo transported by the first car, which is 35% of the total cargo: - First car's cargo = 35% of 40 tons - First car's cargo = 0.35 * 40 tons - First car's cargo = 14 tons

2. Let's assume the third car transported x tons of cargo. Since the second car transported 2 tons more than the third car, the second car transported (x + 2) tons of cargo.

3. The total cargo transported by the three cars is 40 tons. Therefore, we can write the equation: - First car's cargo + Second car's cargo + Third car's cargo = Total cargo - 14 tons + (x + 2) tons + x tons = 40 tons

4. Simplify the equation: - 14 tons + 2x + 2 tons = 40 tons - 2x + 16 tons = 40 tons

5. Subtract 16 tons from both sides of the equation: - 2x = 40 tons - 16 tons - 2x = 24 tons

6. Divide both sides of the equation by 2: - x = 12 tons

Now we know that the third car transported 12 tons of cargo. Since the second car transported 2 tons more than the third car, the second car transported 12 + 2 = 14 tons of cargo.

Answer

Therefore, each car transported the following amounts of cargo: - The first car transported 14 tons of cargo. - The second car transported 14 tons of cargo. - The third car transported 12 tons of cargo.

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