Question

Решите пожалуйста 1)x*22=396 2) 318:x=6 3)19x-7x=144 И задачу В автомобиль погрузили 5 одинаковых мешков сахара и 3 одинаковых мешка муки. Оказалось что общая масса груза равна 370 кг. Какова масса одного мешка муки если масса одного мешка сахара равна 50 кг?

Answer 1

1)x*22=396
   х=396/22
   x= 18
2) 318:x=6
     x= 318/6
    x=53
3)19x-7x=144
    12x=144
    x=144/12
     x=12  

Answer 2

Problem 1: x * 22 = 396

To solve this equation, we need to isolate the variable x. We can do this by dividing both sides of the equation by 22.

Dividing both sides of the equation by 22, we get:

x = 396 / 22

Simplifying the right side of the equation:

x = 18

Therefore, the value of x that satisfies the equation is 18.

Problem 2: 318 : x = 6

To solve this equation, we need to isolate the variable x. We can do this by multiplying both sides of the equation by x.

Multiplying both sides of the equation by x, we get:

318 = 6 * x

Simplifying the right side of the equation:

318 = 6x

To isolate x, we can divide both sides of the equation by 6:

318 / 6 = x

Simplifying the left side of the equation:

53 = x

Therefore, the value of x that satisfies the equation is 53.

Problem 3: 19x - 7x = 144

To solve this equation, we need to combine like terms on the left side of the equation.

Combining like terms, we get:

12x = 144

To isolate x, we can divide both sides of the equation by 12:

12x / 12 = 144 / 12

Simplifying both sides of the equation:

x = 12

Therefore, the value of x that satisfies the equation is 12.

Problem 4: Mass of one bag of flour

In this problem, we are given that 5 bags of sugar and 3 bags of flour have a total mass of 370 kg. We need to find the mass of one bag of flour, given that the mass of one bag of sugar is 50 kg.

Let's assume the mass of one bag of flour is x kg.

The total mass of the bags of sugar is 5 * 50 kg = 250 kg.

The total mass of the bags of flour is 3 * x kg = 3x kg.

According to the problem, the total mass of the bags of sugar and flour is 370 kg.

Therefore, we can write the equation:

250 kg + 3x kg = 370 kg

To solve for x, we need to isolate it on one side of the equation. We can do this by subtracting 250 kg from both sides:

3x kg = 370 kg - 250 kg

Simplifying both sides of the equation:

3x kg = 120 kg

To isolate x, we can divide both sides of the equation by 3:

3x kg / 3 = 120 kg / 3

Simplifying both sides of the equation:

x kg = 40 kg

Therefore, the mass of one bag of flour is 40 kg.
