Question

Три машины-цементовоза , сделав одинаковое число рейсов, привезли на стройплощадку 609 т цемента. Первая машина за один рейс перевозила 8 т цемента, вторая-13,5 т., третья-22 т. Сколько цемента перевезла каждая машина?

Answer 1

8+13,5+22=43,5

609/43,5=14

8*14=112        (1 машина)

13,5*14=189  (2 машина)

22*14=308     (3 машина)

Проверка!     

112+189+308=609

Answer 2

Calculation of Cement Transported by Each Truck

To determine how much cement each truck transported, we need to calculate the number of trips made by each truck and the amount of cement carried per trip.

Let's denote the number of trips made by the first truck as x, the number of trips made by the second truck as y, and the number of trips made by the third truck as z.

Given the following information: - The first truck carried 8 tons of cement per trip. - The second truck carried 13.5 tons of cement per trip. - The third truck carried 22 tons of cement per trip. - The total amount of cement transported by all three trucks is 609 tons.

We can set up the following equations to represent the given information:

Equation 1: x + y + z = total number of trips Equation 2: 8x + 13.5y + 22z = total amount of cement

We can solve these equations simultaneously to find the values of x, y, and z.

Let's solve the equations:

From Equation 1, we have: x + y + z = total number of trips

From Equation 2, we have: 8x + 13.5y + 22z = total amount of cement

Substituting the given values: 8x + 13.5y + 22z = 609

Using the search results provided by You.com, we can see that the total amount of cement transported is 609 tons.

Now, let's solve the equations to find the values of x, y, and z.
