Question

За 6 ч работы ученик сделал столько же деталей сколько мастер за 4 часп известно ,чтл мастер изготовлял в час на 5 деталей больше,чем ученик ,сколько деталей в час изготовлял ученик?решите пожалуйста как можно быстрей у меня 10 минут

Answer 1

Ученик изготавливал x деталей за час, мастер (x+5) деталей. За 6 часов ученик сделает 6x деталей, мастер за 4 часа 4*(x+5) деталей. Сделают поровну.
6x = 4*(x+5)
6x = 4x+20
6x-4x = 20
2x = 20
x = 10

Ответ: ученик за час изготавливал 10 деталей.

Answer 2

Problem Analysis

We are given that a student and a master worked for 6 hours and 4 hours, respectively, and produced the same number of parts. It is also known that the master produced 5 more parts per hour than the student. We need to determine how many parts the student produced per hour.

Solution

Let's assume that the student produced x parts per hour. Since the master produced 5 more parts per hour than the student, the master produced x + 5 parts per hour.

We can set up the following equation based on the given information:

6x = 4(x + 5)

Now, let's solve this equation to find the value of x.

Calculation

6x = 4(x + 5)

Expanding the equation: 6x = 4x + 20

Subtracting 4x from both sides: 2x = 20

Dividing both sides by 2: x = 10

Answer

The student produced 10 parts per hour.
