Question

Двоє робітників, працюючии разом однакову кількість днів, виготовили 725 деталей.Перший робітник виготовляв за день 17 деталей,а другий 8. Скільки деталей виготовив кожен робітник окремо? ПРОШУ ПОМОГИТЕОЧЕНЬ НУЖНО​

Answer 1

Ответ:

Пошаговое объяснение:

1) 17+8=25(деталей)-виготовляли обидва робітників за 1 день;

2) 725:25=29(днів) - вони працювали;

3) 29*17=493 (деталі) - виготовив один робітник;

4)29*8=232 (деталі) - виготовив інший робітник

Answer 2

Problem Analysis

We are given that two workers worked together for the same number of days and produced a total of 725 parts. The first worker produced 17 parts per day, while the second worker produced 8 parts per day. We need to determine how many parts each worker produced individually.

Solution

Let's assume that the first worker produced x parts and the second worker produced y parts.

From the given information, we can set up the following equations:

Equation 1: x + y = 725 (since the total number of parts produced is 725) Equation 2: x/17 = y/8 (since the first worker produced 17 parts per day and the second worker produced 8 parts per day)

To solve this system of equations, we can use substitution or elimination.

Let's solve it using substitution:

From Equation 2, we can express x in terms of y: x = (17/8)y

Substituting this value of x into Equation 1, we get: (17/8)y + y = 725 (25/8)y = 725 y = (8/25) * 725 y = 290

Now, substituting the value of y back into Equation 2, we can find x: x = (17/8) * 290 x = 493.75

Since the number of parts produced must be a whole number, we can round x down to the nearest whole number: x = 493

Answer

Therefore, the first worker produced 493 parts and the second worker produced 290 parts.
