Answer:

20 members of the rappelling club are going on the trip

Explanation:

Total cost of the trip is $540.

If only one person goes, the cost is $540.

We can make the total number of people going x since we are not given.

Therefore, each member would pay (540/x)

We can also rep 7 with non members since the number is given as 7

Total people going= Members + non members.

Therefore, the cost per person is now (540/x+7).

Problem.

540/x -540/x +7 = 7

Multiply each with lowest common denominator.

When you expand, you get

540(x+7) - x(540)/x(x+7) =7

Simplify multiplication.

540x+3780-540x=7(x^2+7x)

Combine like terms

540x-540x+3780=7x^2+49x

3780=7x^2+49x

7x^2+49x-3780= 0

When we divide through by 7, we have

x^2+7x-540

Factorize, we have

(x^2+27x)-(20x-540)=0

x(x+27)-20(x+27)=0

(x-20)(x+27)=0

x is therefore 20 or -27

Since we know -27 cannot be a reasonable answer hence must be excluded.

The exact number of the people going on the trip is 20.

How do maps help us understand the development of civilizations and how agriculture influenced the process?
Allushta [10]

Answer:

ExplaOverview

The term civilization refers to complex societies, but the specific definition is contested.

The advent of civilization depended on the ability of some agricultural settlements to consistently produce surplus food, which allowed some people to specialize in non-agricultural work, which in turn allowed for increased production, trade, population, and social stratification.

The first civilizations appeared in locations where the geography was favorable to intensive agriculture.

Governments and states emerged as rulers gained control over larger areas and more resources, often using writing and religion to maintain social hierarchies and consolidate power over larger areas and populations.

Writing allowed for the codification of laws, better methods of record-keeping, and the birth of literature, which fostered the spread of shared cultural practices among larger populations.

Degrees of complexity

Today, almost every city has a supermarket with a wide variety of available foods. We take for granted the fact that people have different types of jobs and that governments exist. But, reliable food sources, specialized work, and governments did not exist for most of human history! They are the products of historical processes that began with the first civilizations several thousand years ago.

A civilization is a complex society that creates agricultural surpluses, allowing for specialized labor, social hierarchy, and the establishment of cities. Developments such as writing, complex religious systems, monumental architecture, and centralized political power have been suggested as identifying markers of civilization, as well. When we see these changes occur, we should stop and ask, “Did people institute these practices because they were beneficial, or were they forced on them?” Historians debate this very question, trying to determine whether civilization was a bottom-up or top-down development.^1
