11-3(a-2)=27 I NEED TO SHOW WORK HELP

Answers

Answer 1

Answer:

3.3 recurring

Step-by-step explanation:

1) expand bracket

11-3a+6=27

2)rearrange equation

11+6=27+3a

11+6-27=3a

17-27=3a

-10=3a

-10/3=a

a=3.3 recurring

Answer 2

Answer:

a= - [tex]\frac{10}{3}[/tex] or -3.33

Step-by-step explanation:

[tex]11-3(a-2)=27[/tex]

subtract 11 on both sides; 27-11=16

[tex]-3(a-2)=16[/tex]

divide both sides by -3

[tex](a-2)=-\frac{16}{3}[/tex]

add 2 on both sides

[tex]a=-\frac{16}{3} +2[/tex]

a=[tex]-\frac{10}{3}[/tex]

Answer: Dividing the number by 1000

When you move the decimal, add a 0.
The decimal is moved 3 times, there are 3 zeros. When you move left, the number is getting smaller so it is division.

Hope this helps ʕ•ᴥ•ʔ

Answer:

See below

Step-by-step explanation:

So you are moving the decimal to the right, right?

This action would make the number bigger.

For this explanation I will use the example 7.2

So lets move the decimal 3 to the right.

You get 7200.

Now try dividing 7200 by 100 = 72

This did not get us the original # 7.2

Now lets divide 7200 by 1000 = 7.2

Now that we got the original #, switch the operation and multiply 7.2 by 1000

7.2 x 1000 = 7200

Answer = multiplying the number by 1,000

so, it seems like the second one and the very last one is correct. pi is always rational and it never stops and never repeats. 7 is irrational because 2 of the same numbers cannot go in it. what I’m meaning is that 2,3,4,5,6 cannot go into 7.

The true statements are,

π is irrational because π is a repeating decimal.

7√ is irrational because 7 is not a perfect square.

7.1234… is irrational because it is a nonterminating, nonrepeating decimal.

7√ is rational because 7 is not a perfect square.

What are irrational numbers?

Irrational number are real numbers that cannot be expressed as a ratio of two integers.

When an irrational number is expressed in decimal form, it goes on forever without repeating.square roots like √2 ,√3, √5.. are irrational number.

Now we have,

→π is irrational because π is a repeating decimal.

Since, the value of π is called as infinite decimal-after the decimal point the digits go on forever and repeating.

Hence π is irrational.

⇒This statement is true.

→√7 is irrational because 7 is not a perfect square.

Since, 7 is a prime number this means 7 is without its pair and is not in the power of 2.

Therefore,√7 is irrational

⇒This statement is true.

→7.1234… is irrational because it is a non terminating, non repeating decimal.

Since,the value of decimal in 7.1234… goes on forever and repeating.

Therefore,7.1234… is irrational.

⇒This statement is true.

→√7 is rational because 7 is not a perfect square.

Since, 7 is a prime number this means 7 is without its pair and is not in the power of 2.

Therefore,√7 is irrational

The ages of Edna, Ellie, and Elsa are consecutive integers. The sum of their ages is 114.
What are their ages?

Answers

x = Edna's age

x + 1 = Ellie's age

x + 2 = Elsa's age

the sum of their ages = 114

Let's set all of their ages equal to 114

x + x + 1 + x + 2 = 114

Combine like terms

3x + 3 = 114

Subtract 3 from both sides

3x = 111

Divide both sides by 3

x = 37

Edna's age = x = 37 years old

Ellie's age = x + 1 = 37 + 1 = 38 years old

Elsa's age = x + 2 = 37 + 2 = 39 years old

You may not think earthquakes and volcanoes can go together, but they are unlikely friends, creating sensations under the earths surface. Most earthquakes occur because of the movement of tectonic plates previously described. Sometimes earthquakes happen below a volcano. This happens because magma, which is hot molten rock beneath the earths surface, pushes on rock until it breaks the rock and seeps into it. Then, the magma builds more pressure until it leaks more magma into the crack. Little earthquakes happen each time the rock breaks and lets in more magma. These little earthquakes are too small to feel. They are called harmonic tremors, perhaps because of their constant release of energy, like one long song played underground. What does the underlined analogy mean in this paragraph? A) When little earthquakes occur, they make sounds much like musical harmonies do. B) The same amount of energy is required to play harmonic songs as it is to create a little earthquake. C) Much like music that might play softly in the background, little earthquakes tremor underground without much notice.

Africa has influenced and has also been influenced by other continents. We can see this in its willingness to adapt to the ever-changing modern world rather than staying rooted to their static culture. This, of course, also affects their art and literature. As we know, African literature, specifically the oral type, is influenced by the sub- saharan cultures that have participated in the cultures of the United States.The traditions of Africa are veryunique because they are different from other countries and other continents. According to research Africans celebrate special events mostly through dancing. By researching thru the Internet, Oral Practices have been the most practiced tradition in Africa. African Culture tells us that they also love making artworks. African Art is another significant embodiment of the ways and means Africans communicate and propagate their ideas of life.
