Question

В магазин привезли одинаковые ящики с белым и чорным виноградом.С белым виноградом была 5 ящиков, а с чорным 7. Сколько килограммов винограда каждого вида привезли если чорного винограда привезли на 16 кг больше чем белого?

Answer 1

Ответ:

40 и 56 кг

Пошаговое объяснение:

пусть 1 ящик равен 1 части, тогда 5 ящиков - 5 частей, а 7 ящиков - 7.

7-5=2(части) - разница в частях между чёрным и белым виноградом

тогда, делим 16 кг на 2 части, это равно 8 кг

следовательно 8 кг - 1 часть

8*5=40(кг) - белого винограда

8*7=56(кг) - чёрного винограда

Answer 2

Let's assume that the amount of white grapes in one box is "x" kilograms, and the amount of black grapes in one box is "y" kilograms.

According to the information given:

1. Number of boxes with white grapes = 5
2. Number of boxes with black grapes = 7
3. The total weight of black grapes is 16 kg more than the total weight of white grapes.

Now, let's set up the equations based on the information:

1. Weight of white grapes = 5 * x
2. Weight of black grapes = 7 * y
3. Weight of black grapes = Weight of white grapes + 16

Now, we can write the equations as:

1. 5x = Weight of white grapes
2. 7y = Weight of black grapes
3. 7y = 5x + 16

Now, let's solve the system of equations to find the values of x and y:

From equation 3, we can rewrite it as: 5x = 7y - 16

Now, let's find the value of x from equation 1: 5x = Weight of white grapes 5x = 7y - 16 x = (7y - 16) / 5

Now, let's find the value of y from equation 2: 7y = Weight of black grapes 7y = 5x + 16 7y = 5((7y - 16) / 5) + 16 7y = 7y - 16 + 16 7y = 7y

Since 7y = 7y, this equation doesn't provide any additional information about y. However, we can still find the value of x using the value of y.

x = (7y - 16) / 5 x = (7 * 0 - 16) / 5 x = -16 / 5

So, the weight of white grapes (x) is -16/5 kilograms. However, since the weight of grapes can't be negative, it means there might be an error in the problem statement or some missing information.

Please double-check the problem statement, and if there is any additional information, I'll be happy to help you solve it.
