Question

дрот длиной 624 м разрезали на две части , первая с которыч в 5 раз короче от второй. Найти длину первой части.

Answer 1

Х- первая часть грота, 5*х - вторая часть грота х+5х=624 6х=624 х=624/6 х=104 м - первая часть 104 *5 = 520 м. - вторая часть грота

Answer 2

Пусть первая часть х м, тогда вторая 5х м. 5х+х=624 6х=624 х=104 м Ответ: 104м

Answer 3

Problem Analysis

To solve this problem, we need to find the length of the first part of the wire after it has been cut into two pieces, with the first part being 5 times shorter than the second part.

Solution

Let's denote the length of the first part as x and the length of the second part as y. We are given that the total length of the wire is 624m, and the first part is 5 times shorter than the second part.

We can set up the following equations based on the given information: 1. x + y = 624 (the sum of the lengths of the two parts is equal to the total length of the wire) 2. x = (1/5)y (the length of the first part is 1/5 of the length of the second part)

Now, we can solve these equations to find the lengths of the two parts.

Calculation

Substitute the value of x from equation 2 into equation 1: (1/5)y + y = 624 Simplify the equation: (6/5)y = 624 Multiply both sides by 5/6 to solve for y: y = 624 * 5/6

Now, we can find the length of the first part by substituting the value of y back into equation 2: x = (1/5) * (624 * 5/6)

Result

After solving the equations, we find that: - y = 520m - x = 104m

So, the length of the first part is 104m.
