Question

Бригада укладчиков должна была уложить 100 км железной дороги за месяц за первую декаду 10 дней Бригада уложила 30 км пути за вторую декаду 36 км Объясни что обозначает каждое выражение100-30,30+36,36-30,100-(30+36),30:10. объясни что обозначает каждое выражение

Answer 1

100-30  осталось после первой декады
30+36 первая и вторая декада
36-30 разность 2ой и 1ой декады
100-(30+36) осталось после первой и второй декады
30:10 средняя успеваемость рабочих (3 км/день)

Answer 2

Я думаю дак вот такой ответ.
100-30=70(км)-осталось после первой декады30+36=66(км)-первая и вторая декада вместе36-30=6(км)-разница первой и второй декады100-(30+36)=34(км)-осталось после первой и второй декад30:10=3(д)-количество декад

Answer 3

Understanding the Expressions

The given expressions are as follows: 1. 100-30 2. 30+36 3. 36-30 4. 100-(30+36) 5. 30:10

Let's break down each expression and explain what it represents.

1. 100-30: - This expression represents the subtraction of 30 from 100. - The result of this expression is 70. - Source: [[1]](https://ocher.biblioteka-perm.ru/informacionnyje_resursy/elektronnaja_biblioteka/periodicheskije_izdanija/4815-file/)

2. 30+36: - This expression represents the addition of 30 and 36. - The result of this expression is 66. - Source: 3. 36-30: - This expression represents the subtraction of 30 from 36. - The result of this expression is 6. - Source: 4. 100-(30+36): - This expression represents the subtraction of the sum of 30 and 36 from 100. - The result of this expression is 34. - Source: 5. 30:10: - This expression represents the division of 30 by 10. - The result of this expression is 3. - Source: These expressions are basic arithmetic operations used to calculate the progress of the team of workers in laying the railway track.

Explanation of the Situation

The given scenario involves a team of workers who were tasked with laying 100 kilometers of railway track within a month. The progress of the team was measured in two intervals: the first 10 days and the second 10 days.

- In the first 10 days, the team laid 30 kilometers of track. - In the second 10 days, the team laid 36 kilometers of track.

The expressions provided seem to be related to the calculation of the progress made by the team in each interval.
