Question

Масса первого детали в 7 раз больше чем масса второго детали. Масса второго детала на 90 кг меньше масса второго детали

Answer 1

Х-масса 2й детали
7х-масса 1й детали
уравнение:
7х=х+90
6х=90
х=15
15*7=105кг масса 1й детали
105+15=120кг масса 2 и 1 деталей

Answer 2

Масса первой детали в 7 раз больше, чем масса второй детали. Масса второй детали на 90 кг меньше массы первой детали.

Calculating the Mass of the First and Second Parts

To calculate the mass of the first and second parts, we can set up a system of equations based on the given information.

Let's assume the mass of the second part is represented by x kg. According to the given information, the mass of the first part is 7 times greater than the mass of the second part. Therefore, the mass of the first part can be represented as 7x kg.

Additionally, we know that the mass of the second part is 90 kg less than the mass of the first part. This can be represented as:

7x - 90 = x

Simplifying the equation, we get:

6x = 90

Solving for x, we divide both sides of the equation by 6:

x = 15

Therefore, the mass of the second part is 15 kg.

To find the mass of the first part, we can substitute the value of x into the equation:

7x = 7 * 15 = 105

Therefore, the mass of the first part is 105 kg.

Answer:

The mass of the first part is 105 kg, and the mass of the second part is 15 kg.
