Question

В двух пакетах 840г конфет. в одном из них конфет в 2 раза больше , чем в другом. Сколько граммов конфет в каждом пакете???

Answer 1

пусть х г- в одном пакете, 

тогда 2х г- во втором.

х+2х=840

3х=840

х=280г в меньшем 

2х=560г в большем 

проверка

560+280=840 г всего 

Answer 2

х грамм конфет в 1 пакете

2х грамм конфет во 2 пакете

х+2х=840

3х=840

х=840:3

х=280 грамм в 1 пакете

280*2= 560 грамм во 2 пакете

Answer 3

Calculating the Weight of Candies in Each Packet

To solve this problem, we can set up a system of equations based on the information provided.

Let's assume: - The weight of candies in the first packet is represented by x grams. - The weight of candies in the second packet is represented by y grams.

Given that the weight of candies in one packet is twice the weight of candies in the other packet, we can express this relationship as: - x = 2y.

Additionally, we know that the total weight of candies in both packets is 840 grams: - x + y = 840.

Solving the System of Equations

We can use the substitution method to solve the system of equations.

Substitute the value of x from the first equation into the second equation: - 2y + y = 840 - 3y = 840 - y = 280.

Now that we have the value of y, we can find the value of x using the first equation: - x = 2y - x = 2 * 280 - x = 560.

Answer:

- The weight of candies in the first packet is 560 grams. - The weight of candies in the second packet is 280 grams.
