Paulo's economics course requires two papers ? ? one long and one short ? ? throughout the semester. the number of pages, l l, in the long paper is one more than two times the number of pages, s s, in the short paper. if the total number of pages for both papers is 4 0 40, how many pages must be in the long paper?

27 pages.

Step-by-step explanation:

Let l be the number of pages in the long paper and s be the number of pages in the short paper.

We have been given that the total number of pages for both papers is 40. We can represent this information in an equation as:

We are also told that the number of pages in the long paper is one more than two times the number of pages in the short paper. We can represent this information in an equation as:

We will use substitution method to solve system of linear equations.

From equation (1) we will get,

Upon substituting this value in equation (2) we will get,

Upon adding 2l to both sides of our equation we will get,

Let us divide both sides of our equation by 3 we will get,

Therefore, there must be 27 pages in the long paper.

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
