Mark think of a number mark doubles it and add 2.9 to get answer of 30.6 form an equation with x from the information

Answers

Answer:

2x + 2.9 = 30.6

Step-by-step explanation:

We are to represent the unknown number that Mark thinks of with x

If Mark doubles this unknown number, he multiplies it by 2 and the unknown number becomes - 2x

He then adds 2.9

The equation becomes 2x + 2.9

The answer of the above equation is 30.6

This gives : 2x + 2.9 = 30.6

Use Elimination to solve the system below, find X!!!

3x + 3y = 15

2x + 3y = 13




x = 3
x = 3

x = 2
x = 2

Write the Quadratic Formula for the quadratic equation.

Answers

Answer:

[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

Step-by-step explanation:

Hello!

Let's start with the given equation and work our way towards x.

Solve for x[tex]ax^2 + bx + c = 0[/tex]

Divide both sides by a

[tex]a(x^2 + \frac bax + \frac ca) = 0[/tex]        [tex]x^2 + \frac bax + \frac ca = 0[/tex]

Move c/a to the other side

[tex]x^2 + \frac bax = -\frac ca[/tex]

At the step, we have to use the Completing the Square method.

[tex]x^2 + \frac bax + (\frac{b}{2a})^2 = -\frac ca + (\frac b{2a})^2[/tex][tex]x^2 + \frac bax + \frac{b^2}{4a^2} = -\frac ca + \frac {b^2}{4a^2}[/tex][tex](x + \frac b{2a})^2= -\frac ca + \frac{b^2}{4a^2}[/tex]

Multiply -c/a by 4a and add the two fractions

[tex](x + \frac b{2a})^2= \frac{b^2 - 4ac}{4a^2}[/tex]

Square Root both sides

[tex]\sqrt{(x + \frac b{2a})^2}= \sqrt{\frac{b^2 - 4ac}{4a^2}}[/tex][tex]x + \frac b{2a} = \pm\frac{\sqrt{b^2 - 4ac}}{2a}}[/tex]

Subtract b/2a

[tex]x = \pm \frac{ \sqrt{b^2 - 4ac}}{2a} - \frac b{2a}[/tex][tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

And that's the derivation of the Quadratic Formula.

Step-by-step explanation:

STEP 1: Convert interest rate of 1.5% per month into rate per year.

STEP 2: Convert 210 days into years.

STEP 3: Find an interest by using the formula , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.

In this example P = $12000, i = 18% and t = 0.57534 years, so

Priscilla can make 2 bracelets in 16 minutes. At this rate, how many bracelets can she make in 64 minutes?

Answers

Answer:

8 bracelets.

Step-by-step explanation:

First, find out how long it'll take Priscilla to make on bracelet. It is given that she can make 2 bracelets in 16 minutes. Divide 16 with 2:

16/2 =8

Priscilla takes 8 minutes to make 1 bracelet. Divide 64 with 8 to find the amount of bracelets Priscila can make:

64/8 = 8

8 bracelets is your answer.

~

Given: Priscilla makes 2 bracelets in 16 minutes

To Attain: How many Bracelets she will make in 64 minutes?

⠀⠀⠀⠀⠀⠀__________________

Solution:

Firstly, We will divide the 16min with 2 to find the that how many time taken to make 1 bracelets. then we will multiply the rate with 64min to find how many bracelets she will make! Let's do it•

C. 244°

Step-by-step explanation:

Angle formed by two tangents is equal to half of the difference of intercepted arcs:

m∠C = 1/2(arcAXB - arcAB)64° = 1/2(mAXB - mAB)mAXB - mAB = 128°

The sum of the same two arcs is a full circle:

mAXB + mAB = 360°

Add the two equations together:

2mAXB = 360° + 128°2mAXB = 488°mAXB = 244°

Correct choice is C

What is the difference between a concentration camp and an extermination camp?help Please help from A Bachelors Complaint of the Behaviour of Married Peopleby Charles LambAs a single man, I have spent a good deal of my time in noting down the infirmities of Married People, to console myself for those superior pleasures, which they tell me I have lost by remaining as I am.I cannot say that the quarrels of men and their wives ever made any great impression upon me, or had much tendency to strengthen me in those anti-social resolutions, which I took up long ago upon more substantial considerations. What oftenest offends me at the houses of married persons where I visit, is an error of quite a different description;it is that they are too loving.Not too loving neither: that does not explain my meaning. Besides, why should that offend me? The very act of separating themselves from the rest of the world, to have the fuller enjoyment of each others society, implies that they prefer one another to all the world.But what I complain of is, that they carry this preference so undisguisedly, they perk it up in the faces of us single people so shamelessly, you cannot be in their company a moment without being made to feel, by some indirect hint or open avowal, that you are not the object of this preference. Now there are some things which give no offence, while implied or taken for granted merely; but expressed, there is much offence in them. If a man were to accost the first homely-featured or plain-dressed young woman of his acquaintance, and tell her bluntly, that she was not handsome or rich enough for him, and he could not marry her, he would deserve to be kicked for his ill manners; yet no less is implied in the fact, that having access and opportunity of putting the question to her, he has never yet thought fit to do it. The young woman understands this as clearly as if it were put into words; but no reasonable young woman would think of making this the ground of a quarrel. Just as little right have a married couple to tell me by speeches, and looks that are scarce less plain than speeches, that I am not the happy man,the ladys choice. It is enough that I know I am not: I do not want this perpetual reminding.The display of superior knowledge or riches may be made sufficiently mortifying; but these admit of a palliative. The knowledge which is brought out to insult me, may accidentally improve me; and in the rich mans houses and pictures,his parks and gardens, I have a temporary usufruct at least. But the display of married happiness has none of these palliatives: it is throughout pure, unrecompensed, unqualified insult.Marriage by its best title is a monopoly, and not of the least invidious sort. It is the cunning of most possessors of any exclusive privilege to keep their advantage as much out of sight as possible, that their less favoured neighbours, seeing little of the benefit, may the less be disposed to question the right. But these married monopolists thrust the most obnoxious part of their patent into ourfaces.Nothing is to me more distasteful than that entire complacency and satisfaction which beam in the countenances of a new-married couple, in that of the lady particularly: it tells you, that her lot is disposed of in this world: that you can have no hopes of her. It is true, I have none; nor wishes either, perhaps: but this is one of those truths which ought, as I said before, to be taken for granted, not expressed. The excessive airs which those people give themselves, founded on the ignorance of us unmarried people, would be more offensive if they were less irrational. We will allow them to understand the mysteries belonging to their own craft better than we who have not had the happiness to be made free of the company: but their arrogance is not content within these limits. If a single person presume to offer his opinion in their presence, though upon the most indifferent subject, he is immediately silenced as an incompetent person. Nay, a young married lady of my acquaintance, who, the best of the jest was, had not changed her condition above a fortnight before, in a question on which I had the misfortune to differ from her, respecting the properest mode of breeding oysters for the London market, had the assurance to ask with a sneer, how such an old Bachelor as I could pretend to know any thing about such matters.All the following are mocked in the passage EXCEPTA.intelligence gained as a result of marriageB.undisguised preference of married couples for their spouseC.condescension of married females to bachelorsD.married individuals presumptive knowledgeE.overt cruelty of married couples to unattractive unmarried femalesPlease select the best answer from the choices providedABCDE PLEASE ANSWER HURRY!!
