Question

В двух мотках было одинаковое количество провода .когда от первого мотка отрезали 36 метров сантиметров а от второго 16метров то в первом мотке осталось провода в 2 раза меньше чем во втором.сколько метров провода было в каддом мотке сначала

Answer 1

1) 36-16=20(м.) 2) 20+36=56(м.) 3) 20*2=40(м.) 4) 40+16=56(м.) ответ:56метров

Answer 2

Problem Analysis

We are given two coils of wire with the same initial length. When 36 meters and 16 meters are cut from the first and second coils respectively, the length of the wire remaining in the first coil is half the length of the wire remaining in the second coil. We need to determine the initial length of wire in each coil.

Solution

Let's assume the initial length of wire in each coil is x meters.

According to the problem, when 36 meters are cut from the first coil, the length of wire remaining is half the length of the wire remaining in the second coil after cutting 16 meters.

Mathematically, we can represent this as:

x - 36 = (x - 16) / 2

To solve this equation, we can simplify it as follows:

2(x - 36) = x - 16

Simplifying further:

2x - 72 = x - 16

x = 56

Therefore, the initial length of wire in each coil was 56 meters.

Answer

The initial length of wire in each coil was 56 meters.
