Question

Журналы дороже газеты в 2 раза а вмести они стоят 84 Сколько стоят журналы и газеты отдельности​

Answer 1

Ответ:

28,56.

Пошаговое объяснение:

Пусть х стоят газеты, тогда журналы 2х

2х+х=84

3х=84

х=28

Итак, газеты стоят 28,значит журналы 28*2=56.

Answer 2

Let's assume the cost of the newspaper (газеты) is represented by the variable "n" and the cost of the magazine (журналы) is represented by the variable "m."

According to the given information, "Журналы дороже газеты в 2 раза," which means the cost of magazines is twice the cost of newspapers. Mathematically, we can express this as:

m = 2n

And the total cost of both the newspaper and magazine together is 84:

n + m = 84

Now, we can substitute the value of "m" from the first equation into the second equation:

n + 2n = 84

Combine like terms:

3n = 84

Now, solve for "n":

n = 84 / 3 n = 28

So, the cost of the newspaper (газеты) is 28 units.

Next, we can find the cost of the magazine (журналы) using the first equation:

m = 2n m = 2 * 28 m = 56

Therefore, the cost of the magazine is 56 units.

To summarize: Cost of newspaper (газеты) = 28 units Cost of magazine (журналы) = 56 units
