Question

На складе было 392 банки вишнёвого, малинового и клубничного варенья. Банок с вишнёвым вареньем в 3 раза больше, чем малинового, а клубничного было 80 банок. Сколько весит вишнёвое варенье, если в каждой банке его 800 г?

Answer 1

3x+x+80=392
4x=312(392-80)
x=78
2)78*3=234
ответ:вишневых=234
малиновых=78
клубничных=80

Answer 2

Calculating the Weight of Cherry Jam

To calculate the weight of cherry jam, we can use the information provided about the number of jars of cherry, raspberry, and strawberry jam, along with the weight of each jar.

Given: - Number of cherry jam jars = 3x - Number of raspberry jam jars = x - Number of strawberry jam jars = 80 - Weight of each jar of cherry jam = 800g

We can start by finding the value of x, which represents the number of raspberry jam jars.

Calculating the Number of Raspberry Jam Jars

The number of cherry jam jars is 3 times the number of raspberry jam jars. Additionally, there are 80 strawberry jam jars.

Let's use algebra to solve for x: - Number of cherry jam jars = 3x - Number of raspberry jam jars = x - Total number of jars = 392 (cherry + raspberry + strawberry)

We can set up the equation: 3x + x + 80 = 392 4x + 80 = 392 4x = 392 - 80 4x = 312 x = 312 / 4 x = 78

So, the number of raspberry jam jars (x) is 78.

Calculating the Weight of Cherry Jam

Now that we know the number of raspberry jam jars, we can calculate the weight of cherry jam.

The weight of cherry jam is given as 800g per jar. Since the number of cherry jam jars is 3 times the number of raspberry jam jars, the total weight of cherry jam can be calculated as: 3x * 800g

Substituting the value of x: 3 * 78 * 800g = 187,200g

The weight of cherry jam is 187,200g.
