Question

Магазин продал за три дня 153 кг калбасы.в первый день он продал в 3 раза меньше,чем во второй и на 2 кг больше чем в третий день.ск кг калбасы продано в третий день?

Answer 1

Пусть в первый день магазин продал - х кг колбасы.     ⇒
Во второй день магазин продал -(3х) кг колбасы.
В третий день магазин продал (х-2) кг колбасы.
x+3x+x-2=153
5x=155
x=31 (кг) - в первый день.
3х=93 (кг) - во второй день.
31-2=29 (кг) - в третий день.
31+93+29=153 (кг).

Answer 2

X- продали во второй день , 1/3x - продали во второй день, 1/x-2 -продали в третий день . Составляет уравнение x+x/3+(x/3-2)=153. После решения этого уравнение получаем что x=93; x/3 -2 =93/3-2=31-2=29. Ответ:29

Answer 3

Calculating the Amount of Sausage Sold on the Third Day

To calculate the amount of sausage sold on the third day, we can use the information provided about the sales over the three days.

Let's denote: - The amount of sausage sold on the first day as x kg. - The amount of sausage sold on the second day as 3x kg. - The amount of sausage sold on the third day as (3x - 2) kg.

We are given that the total amount of sausage sold over the three days is 153 kg. Using this information, we can set up the following equation:

x + 3x + (3x - 2) = 153

Solving for x will give us the amount of sausage sold on the third day.

Solving for the Amount of Sausage Sold on the Third Day

Let's solve the equation to find the value of x and then calculate the amount of sausage sold on the third day.

x + 3x + (3x - 2) = 153

Combining like terms: 7x - 2 = 153

Adding 2 to both sides: 7x = 155

Dividing by 7: x = 22.14

Now that we have the value of x, we can calculate the amount of sausage sold on the third day: (3x - 2) = (3*22.14 - 2) = 66.42 - 2 = 64.42 kg

Answer

The amount of sausage sold on the third day is 64.42 kg.
