If a x 4 = e b / 4 = e c + 4 = e d - 4 = e and a+b+c+d = 100 THEN what is value of 'e'

English

The value of "e" is 16.

a x 4 = e
b / 4 = e
c + 4 = 3
d - 4 = e

a + b + c + d = 100

a x 4 = e
a = e/4

b / 4 = e
b = 4e

c + 4 = e
c = e - 4

d - 4 = e
d = e + 4

e/4 + 4e + e - 4 + e + 4 = 100
e/4 + 4e + 2e = 100
e/4 + 6e = 100
e(1/4 + 6) = 100
e (1/4 + 6*4/4) = 100
e (1/4 + 24/4) = 100
e (25/4) = 100
e = 100 ÷ 25/4
e = 100 x 4/25
e = 400 / 25
e = 16

a = e/4    
⇒ 16/4    ⇒ a =   4
b = 4e     ⇒   4*16  ⇒ b = 64
c = e - 4  ⇒ 16 - 4  ⇒ c = 12
d = e + 4 ⇒ 16 + 4 ⇒ d = 20

a + b + c + d = 100
4 + 64 + 12 + 20 = 100
100 = 100

In a well-developed paragraph, explain how Roosevelt’s letter shows an understanding of his son as the audience. Using examples
Mama L [17]

The use of syntax and diction can be shown in the following ways:

  • The diction that was used in the text would tell about the choice of words that Roosevelt used in his letter.
  • The syntax would show the wway that he used phrases, punctuations and clauses in the formation of sentences.

<h3>What is Roosevelt's letter to his son?</h3>

These were the letters that Theodore Roosevelt wrote showing the deep love and the care that he had for his children.

In general Roosevelt had used these rules of writing in English to show that he had a proper understanding of what his son needed.

How many school text book that i can buy with 5 billion? (this is my civics homework)
Gekata [30.6K]
In order to calculate an accurate answer, we would really need to know the cost
of the textbooks.  We don't know that, and they're not even all the same.

There's a good reason that you were given this question is Civics class, and
before I work on it for you, I want you to promise that you'll go to your teacher
on your way out of class someday soon, and tell your teacher that the guy who
helped you answer this question knows how the teacher feels, and that guy
feels the same way.

Ok.  In order to give you a feeling for the answer, let's try to come up with a
cost that might be a reasonably close figure to use for text books in general.
Now, I know that things have gone completely out of sight since I was in school,
so I'm going to try hard to go high with my numbers.  Let's say that the smallest
textbook costs $20, and the biggest one costs $60, and let's use  $40 as an
estimate for the average cost of every new textbook.

If that's true, then the number of text books that I could buy with $5 billion
would be

(5,000,000,000) / (40) = <u>125 million textbooks</u> ! ! !

If the federal government would spend $5 billion on textbooks, there
would hardly be a high school student anywhere in the USA who didn't
have at least one brand new, up-to-date textbook.

And I can promise you that the book publishers would love it too.

what is the basis for energy in most ecosystems? how much energy is kept as you go up a energy pyramid or a food chain?why?​
zimovet [89]

Answer:

Primary producers—usually plants and other photosynthesizers—are the gateway for energy to enter food webs.

Productivity is the rate at which energy is added to the bodies of a group of organisms—such as primary producers—in the form of biomass.

Gross productivity is the overall rate of energy capture. Net productivity is lower, adjusted for energy used by organisms in respiration/metabolism.

Energy transfer between trophic levels is inefficient. Only about 10% of the net productivity of one level ends up as net productivity at the next level.

Ecological pyramids are visual representations of energy flow, biomass accumulation, and number of individuals at different trophic levels.

Introduction

Have you ever wondered what would happen if all the plants on Earth disappeared—along with other photosynthesizers, like algae and bacteria?

Well, our beautiful planet would definitely look barren and sad. We would also lose our main source of oxygen, that important stuff we breathe and rely on for metabolism. Carbon dioxide would no longer be cleaned out of the air, and—as it trapped heat—Earth might warm up fast. And, perhaps most problematic, almost every living thing on Earth would eventually run out of food and die.

Why would this be the case? In almost all ecosystems, photosynthesizers are the only "gateway" for energy to flow into food webs—networks of organisms that eat one another. If photosynthesizers were removed, the flow of energy would be cut off, and the other organisms would run out of food. In this way, photosynthesizers lay the foundation for every light-receiving ecosystem.

Producers are the energy gateway

Plants, algae, and photosynthetic bacteria act as producers. Producers are autotrophs, or self-feeding organisms, that make their own organic molecules from carbon dioxide. Photoautotrophs, like plants, use light energy to build sugars out of carbon dioxide. The energy is stored in the chemical bonds of the molecules, which are used as fuel and building material by the plant.

The energy stored in organic molecules can be passed to other organisms in the ecosystem when those organisms eat plants or other organisms that have previously eaten plants. In this way, all the consumers—or heterotrophs, other-feeding organisms—of an ecosystem rely on the ecosystem's producers for energy. Consumers include herbivores, carnivores, and decomposers.
