У поли раи и светы есть некоторая сумма денег.У поли 150 р.У Раи в 3 раза меньше денег чем у остальных девочек вместе,а у светы в 2 раза меньше денег чем у остальных девочек вместе.Сколько денег у трех девочек вместе.За х надо принять либо раю,либо свету. ПОМОГИТЕ ПЛИЗ ЗАРАНЕЕ СПАСИБО,решите только с помощью Х.

Answer 1

Пусть у Раи х рублей, тогда у Светы (150+х)/2, то есть у Раи (150+(150+х/2)/3=х
150/3+150/6+х/6=х
50+25+х/6=х 
75=х-х/6 (*6)
450=6х-х
5х=450
х=90 рублей у Раи
(150+90)/2=120 рублей у Светы
150+90+120=360 рублей у трёх девочек 

Answer 2

Problem Analysis

We are given the following information: - The police have 150 rubles. - Rai has three times less money than the rest of the girls. - Sveta has two times less money than the rest of the girls.

We need to find out how much money the three girls have together and decide whether to give the money to Rai or Sveta.

Solution

Let's assume the total amount of money the three girls have together is X.

According to the given information: - Rai has three times less money than the rest of the girls, so Rai has (X - 150)/3 rubles. - Sveta has two times less money than the rest of the girls, so Sveta has (X - 150)/2 rubles.

To find the total amount of money the three girls have together, we can add up the amounts of money each girl has: 150 + (X - 150)/3 + (X - 150)/2 = X

Now, we can solve this equation to find the value of X.

Solving the Equation

To solve the equation, we can simplify it by multiplying through by the common denominator, which is 6:

6 * 150 + 2 * (X - 150) + 3 * (X - 150) = 6 * X

Simplifying further:

900 + 2X - 300 + 3X - 450 = 6X

Combining like terms:

5X - 750 = 6X

Subtracting 5X from both sides:

-750 = X

Therefore, the total amount of money the three girls have together is -750 rubles.

Decision: Giving the Money to Rai or Sveta

Since the total amount of money is negative, it means the girls owe money instead of having money. In this case, it is not possible to give the money to either Rai or Sveta.
