the sum of 3 numbers is 114. the second number is 4 times the third the third number is 6 more than the first

Answers

Answer 1

Answer:

let the three numbers be x,y,z

X= z-6

Y= 4z

Z= z

Step-by-step explanation:

X+Y+Z=114

hence

=z-6+4z+z=114

=collect like times. X= 20-6=14

= z+4z+z=114+6. Y= 20*4=80

=6z=120. . Z= 20

z=20

Answer 2

Answer:

  14 + 20 + 80 = 114

Step-by-step explanation:

Let's begin by representing our 1st number as x.

Then our 2nd number is said to be 6 more than the 1st number, which we can represent as x + 6.

Lastly, our 3rd number is said to be 4 times the 2nd number, which we can represent as 4(x + 6).

Now can write our equation to express the sum of these three numbers as 114 and then solve for x to find the values of these three numbers:

   x + (x + 6) + 4(x + 6) = 114

   x + x + 6 + 4x + 24 = 114

   6x + 30 = 114

   6x = 114 - 30

   6x = 84

     x = 84/6 = 14 (1st number)

     x + 6 = 14 + 6 = 20 (2nd number)

     4(x + 6) = 4(20) = 80 (3rd number)

We can check our answers by adding these numbers up to see if their sum is 114:

    14 + 20 + 80 = 114

    34 + 80 = 114

    114 = 114

Their sum is 114, so we are confident that our three numbers are correct.

Find the equation of the line with slope −2 and that contains the point (−9,−7). Write the equation in the form y=mx+b and identify m and b.

Answers

Answer:

m = -2 which is the slope

b = 2 which is the intercept of the line.

Step-by-step explanation:

We have that the line must pass through the following points (-9, -7). These two points are any two of the numerous points that pass through the straight line.  We can designate variables to each of these points as shown below

Let us take our [tex]y_1 = -7[/tex] and [tex]x_1 = -9[/tex]

Given the slope as [tex](y-y_1)/(x-x_1)=-2[/tex]

[tex](y--7)/(x--9) = -2[/tex]

[tex](y +7)/(x+9) =-2[/tex]

[tex]y +7 = -2(x+9)[/tex]

[tex]y =-2x+2[/tex]

We are given the form:  y=mx+b.

we can compare this with our equation for the line. [tex]y =-2x+2[/tex]

We can see that m = -2 which is the slope and b = 2 which is the intercept of the line.

An airplane flies at an altitude of 14,690 ft while a submarine is submerged at a depth of 521 feet below the surface of the ocean.. What is the difference between these two elevations? Write an algebraic expression for the given applied problem. Simplified the algebraic expression. In the context of the applied problem, explain what your simplified algebraic expression represents.

Answers

Answer:

[tex]d_{T} = d_{A}-d_{S}[/tex]. The algebraic equation represents the distance of the airplane with respecto to the submarine. The distance between the two elevations is 15211 feet.

Step-by-step explanation:

Let be [tex]d[/tex] the distance between a vehicle and sea level, [tex]d > 0[/tex] when vehicle is above sea level, otherwise is below sea level. The difference between airplane and submarine ([tex]d_{T}[/tex]), measured in feet, is obtained by the following expression, that is:

[tex]d_{T} = d_{A}-d_{S}[/tex]

Where:

[tex]d_{A}[/tex] - Distance of airplane with respect to sea level, measured in meters.

[tex]d_{S}[/tex] - Distance of submarine with respect to sea level, measured in meters.

If we know that [tex]d_{A} = 14690\,ft[/tex] and [tex]d_{S} = -521\,ft[/tex], then:

[tex]d_{T} = 14690\,ft - (-521\,ft)[/tex]

[tex]d_{T} = 15211\,ft.[/tex]

The algebraic equation represents the distance of the airplane with respecto to the submarine. The distance between the two elevations is 15211 feet.

The algebraic equation represents the distance of the airplane with respect to the submarine is,

[tex]\rm The \ difference \ between \ both \ elevation = x_a- x_s[/tex]

And the distance between the two elevations is 15,211 feet.

Given that,

An airplane flies at an altitude of 14,690 ft,

While a submarine is submerged at a depth of 521 feet below the surface of the ocean.

We have to determine,

What is the difference between these two elevations?

According to the question,

Let, x be the distance between a vehicle and sea level when the vehicle is above sea level, otherwise is below sea level.

The difference between an airplane [tex]\rm x_a[/tex] and [tex]\rm x_s[/tex] a submarine, measured in feet, is obtained by the following expression, that is:

[tex]\rm The \ difference \ between \ both \ elevation = x_a- x_s[/tex]

Where [tex]\rm x_a[/tex] represents the distance of airplane with respect to sea levels.

And [tex]\rm x_s[/tex] represent the distance of the submarine with respect to sea levels.

Submerged at a depth of 521 feet below the surface of the ocean,

[tex]\rm x_s = -521 \ feet[/tex]

Therefore,

The difference between an airplane [tex]\rm x_a[/tex] and [tex]\rm x_s[/tex] a submarine is,

[tex]\rm The \ difference \ between \ both \ elevation = x_a- x_s\\\\ The \ difference \ between \ both \ elevation = 14,690-(-521)\\\\\rm The \ difference \ between \ both \ elevation = 15,211 \ feet[/tex]

Hence, The difference between these two elevations is 15,211 feet.

Answer:

four

Step-by-step explanation:

there are 4 1/6s in 2/3. 1/6 times four is 4/6. divide numerator and denominator by two to simplify, and you get 2/3. I hope this is correct :)

The number 1/6 s in the fraction 2/3 are 4.

The given fractions are 1/6 and 2/3.

Dividing fractions is nothing but multiplying the fractions by reversing one of the two fraction numbers or by writing the reciprocal of one of the fractions. By reciprocal we mean, that if a fraction is given as a/b, then the reciprocal of it will b/a.

Number of 1/6s are in 2/3

= 2/3 ÷ 1/6

= 2/3 × 6/1

= 4

Verification:

1/6 + 1/6 + 1/6 + 1/6

= 4/6

= 2/3

Therefore, the number 1/6 s in the fraction 2/3 are 4.

Step-by-step explanation:

We are given the equation:

And we want to solve for g, the acceleration due to gravity.

Proceed with algebra:

[tex]\displaystyle \begin{aligned} h & = vt + \frac{1}{2}gt^2 \\ \\ h - vt & = \frac{1}{2}gt^2 \\ \\ gt^2& = 2(h-vt) \\ \\ g &= \frac{2(h-vt)}{t^2}\end{aligned}[/tex]

In conclusion:

[tex]\displaystyle g = \frac{2(h-vt)}{t^2}[/tex]

Answer:

g = [tex]\frac{2(h - vt)}{t^2}[/tex]

Step-by-step explanation:

Given

h = vt + [tex]\frac{1}{2}[/tex] gt² ( subtract vt from both sides )

h - vt = [tex]\frac{1}{2}[/tex] gt² ( multiply both sides by 2 to clear the fraction )

2(h - vt) = gt² ( divide both sides by t² )

[tex]\frac{2(h-vt)}{t^2}[/tex] = g

On a fine morning in June he went out alone to walk in the green woods. He was tired of the noise of the city, and he was glad to get away from it. So, as he walked among the trees, he often stopped to listen to the singing birds, or to look at the wild flowers that grew on every side. Now and then he stooped to pluck a violet, or a primrose, or a yellow buttercup. Soon his hands were full of pretty blossoms. After a while he came to a little meadow in the midst of the wood. Some children were playing there. They were running here and there, and gathering the cowslips that were blooming among the grass. It made the king glad to see the happy children, and hear their merry voices. He stood still for some time, and watched them as they played. Then he called them around him, and all sat down together in the pleasant shade. The children did not know who the strange gentleman was; but they liked his kind face and gentle manners. "Now, my little folks," said the king, "I want to ask you some questions, and the child who gives the best answer shall have a prize." Then he held up an orange so that all the children could see. "You know that we all live in the kingdom of Prussia," he said; "but tell me, to what kingdom does this orange belong?" The children were puzzled. They looked at one another, and sat very still for a little while. Then a brave, bright boy spoke up and said,-- "It belongs to the vegetable kingdom, sir." "Why so, my lad?" asked the king. "It is the fruit of a plant, and all plants belong to that kingdom," said the boy. The king was pleased. "You are quite right," he said; "and you shall have the orange for your prize." He tossed it gayly to the boy. "Catch it if you can!" he said. Then he took a yellow gold piece from his pocket, and held it up so that it glittered in the sunlight. "Now to what kingdom does this belong?" he asked. Another bright boy answered quickly, "To the mineral kingdom, sir! All metals belong to that kingdom." "That is a good answer," said the king. "The gold piece is your prize." The children were delighted. With eager faces they waited to hear what the stranger would say next. "I will ask you only one more question," said the king, "and it is an easy one." Then he stood up, and said, "Tell me, my little folks, to what kingdom do I belong?" The bright boys were puzzled now. Some thought of saying, "To the kingdom of Prussia." Some wanted to say, "To the animal kingdom." But they were a little afraid, and all kept still. At last a tiny blue-eyed child looked up into the king's smiling face, and said in her simple way,-- "I think to the kingdom of heaven." King Frederick William stooped down and lifted the little maiden in his arms. Tears were in his eyes as he kissed her, and said, "So be it, my child! So be it."
