Question

масса автомобилей Таврия и Lanos и Нива вместе 4 тонны 120 кг Какова масса каждого автомобиля если масса Таврии и Lanos 2Т 20 кг а масса ланоса и нивы 3 т 460 кг

Answer 1

1) 4т 120 кг-2т 20 кг=2т 100кг-масса Нивы
2)3т 460кг-2т 100кг=1т 360кг-масса Ланоса
3) 2т 20кг- 1т 360кг=660кг-масса Таврии

Answer 2

To find the mass of each individual car (Tavria, Lanos, and Niva), we can set up a system of equations based on the information provided.

Let:

• Mass of Tavria = x
• Mass of Lanos = y
• Mass of Niva = z

From the given information, we have the following two equations:

1. x + y = 2 tons 20 kg
2. y + z = 3 tons 460 kg

We also know that the total mass of all three cars (Tavria + Lanos + Niva) is 4 tons 120 kg, which can be represented as:

3. x + y + z = 4 tons 120 kg

Now, let's solve the system of equations:

Equation 1: x + y = 2 tons 20 kg Equation 2: y + z = 3 tons 460 kg

Let's subtract Equation 1 from Equation 2 to eliminate y:

(y + z) - (x + y) = (3 tons 460 kg) - (2 tons 20 kg)

Simplifying:

z - x = 1 ton 440 kg

Now, let's add this result to Equation 3:

(z - x) + (x + y + z) = (1 ton 440 kg) + (4 tons 120 kg)

Simplifying:

2z = 5 tons 560 kg

Now, solve for z (mass of Niva):

z = (5 tons 560 kg) / 2 z = 2 tons 780 kg

Now that we have the mass of Niva, let's find the masses of Tavria and Lanos using Equation 1:

x + y = 2 tons 20 kg

Substitute the value of z (2 tons 780 kg):

x + y = 2 tons 20 kg x + y = 2 tons 780 kg - 2 tons 780 kg x + y = 0 kg

Now, since x + y = 0 kg, we know that x = -y.

But we can't have a negative mass, so there might be an error or inconsistency in the information provided. Please double-check the data or let me know if there's any additional information or corrections.
