Answer 2

Answer:

w= 2

Step-by-step explanation:

3-2w+4w=7. We move all terms to the left: 3-2w+4w-(7)=0,  Then we add all the numbers together, and all the variables: 2w-4=0. After, we move all terms containing w to the left, all other terms to the right: 2w=4, w=4/2

Find the measure of <1

Answers

Consider the triangle (in which angle4 is present)

by angle sum property,

20 + 40 + angle4 = 180

60 + angle4 = 180

angle4 = 180 - 60

angle4 = 120

Also,

angle2 = 120 (vertically opposite angles)

angle1 + angle2 = 180 (linear pair)

angle1 + 120 = 180

angle1 = 180 - 120

angle1 = 60

Step-by-step explanation:

A train first travels east for 20 kilometers. Then it turns north and travels for 43 kilometers. Next it goes west for 20 kilometers. Finally, it travels south for an unknown number of kilometers. At the end of the journey, the train is back at the original location. How far did it travel southward?

Answers

Answer: the train traveled 43km southwards

Step-by-step explanation:

First, let's define.

North as the positive y-axis.

East as the positive x-axis.

And the initial position of the train is (0, 0).

Now, we know that:

"A train first travels east for 20 kilometers."

The new position will be:

(0, 0) + (20km, 0) = (20km , 0)

"Then it turns north and travels for 43 kilometers."

The new position will be:

(20km, 0) + (0, 43km) = (20km, 43km)

"Next it goes west for 20 kilometers."

If East if the positive x-axis, then West is the negative x-axis.

The new position of the train will be:

(20km, 43km) + (-20km, 0) = (0, 43km)

Then it travels south for an unknown number of kilometers, such that the final position is the same as the initial position, then if the train goes X kilometers to the south (and because North is the positive y-axis, South will be the negative y-axis), we have:

(0, 43km) + (0, -X) = (0, 0)

(0, 43km - X) = (0, 0)

Then we must have that:

43km - X = 0

43km = X

This means that the train traveled 43km southwards.

What is the solution to this system of equations?

10x-y=53
-13xt92
y=-----------------
2

Answers

Answer:

x = 6, y = -113

Step-by-step explanation:

10x - y = 53 --- Equation 1

y = [tex]\frac{-13x+92}{2}[/tex] --- Equation 2

I will be using the substitution method.

Substitute y = [tex]\frac{-13x+92}{2}[/tex] into Equation 1:

10x - y = 53

10x - ([tex]\frac{-13x+92}{2}[/tex]) = 53

I want to make the denominators on the left side of the equation the same, so I will multiply 10x by 2 so that I can get a fraction.

[tex]\frac{20x}{2}[/tex] - ([tex]\frac{-13x+92}{2}[/tex]) = 53

Now that their denominators are both 2, I can combine the numerators under the same denominator.

[tex]\frac{20x-(-13x+92)}{2}[/tex] = 53

Two minuses, one outside a bracket and one inside makes a plus. One plus and one minus make a minus.

[tex]\frac{20x+13x-92}{2}[/tex] = 53

Evaluate like terms.

[tex]\frac{33x-92}{2}[/tex] = 53

Shift the (÷2) over to the right side and turn into (×2).

33x - 92 = 53 × 2

               = 106

Shift the (-92) over to the right side and turn into (+92).

33x = 106 + 92

      = 198

Find x.

x = 198 ÷ 33

x = 6

Substitute x = 6 into Equation 1:

10x - y = 53

10(-6) - y = 53

Evaluate.

-60 - y = 53

Shift the (-60) over to the right side and turn into (+60).

-y = 53 + 60

   = 113

Find y.

y = -113

If a ladder is to be placed 3 feet from the side of a house. If top of the ladder rests exactly on the edge of the house when it is placed at an angle of 72 degrees from the ground, how long is the ladder to the nearest foot?

Answers

Answer:

7 feet long

Step-by-step explanation:

This set up will give a right angle triangle where;

Length of the ladder is the hypotenuse = x

The distance of the ladder to the house is the adjacent = 3 feet

Angle of elevation theta = 72 degrees

Using the CAH in trigonometry identity;

cos theta = adjacent/hypotenuse

cos 72 = 3/hyp

hyp = 3/cos72

hyp = 3/0.4258

hyp = 7.05 feet

Hence the ladder is approximately 7 feet long

3(x + 2) = -5 - 2(x - 3) *

Answers

Answer:

x = -1

Step-by-step explanation:

3(x + 2) = -5 -2(x-3)

open parenthesis

3 * x + 3 * 2 = -5 +  -2 * x + -2 * -3

3x + 6 = - 5 - 2x + 6

subtract 6 from both sides

3x + 6 - 6 = -5 - 2x + 6

3x = -5 -2x

add 2x from both sides

3x + 2x = -5 - 2x + 2x

5x = -5

divide both sides of the equation by 5

5x/5 = -5/5

x = -5/5

x = -1

True FalseWhen I go into a bank I get rattled. The clerks rattle me; the wickets rattle me; the sight of the money rattles me; everything rattles me. The moment I cross the threshold of a bank and attempt to transact business there, I become an irresponsible idiot. I knew this beforehand, but my salary had been raised to fifty dollars a month and I felt that the bank was the only place for it.So I shambled in and looked timidly around at the clerks. I hadan idea that a person about to open an account must needs consult the manager. I went up to a wicket marked "Accountant." The accountant was a tall, cool [scoundrel]. The very sight of him rattled me. My voice was sepulchral."Can I see the manager?" I said, and added solemnly, "alone." I don't know why I said "alone.""Certainly," said the accountant, and fetched him.The manager was a grave, calm man. I held my fifty-six dollars clutched in a crumpled ball in my pocket."Are you the manager?" I said. . . . I didn't doubt it."Yes," he said."Can I see you," I asked, "alone?" I didn't want to say "alone" again, but without it the thing seemed self-evident.The manager looked at me in some alarm. He felt that I had an awful secret to reveal.Come in here," he said, and led the way to a private room. He turned the key in the lock."We are safe from interruption here," he said; "sit down."We both sat down and looked at each other. I found no voice to speak."You are one of Pinkerton's men, I presume," he said.He had gathered from my mysterious manner that I was a detective. I knew what he was thinking, and it made me worse."No, not from Pinkerton's," I said, seeming to imply that I came from a rival agency. "To tell the truth," I went on, as if I had been prompted to lie about it, "I am not a detective at all. I have come to open an account. I intend to keep all my money in this bank."The manager looked relieved but still serious; he concluded now that I was a son of Baron Rothschild or a young Gould."A large account, I suppose," he said."Fairly large," I whispered. "I propose to deposit fifty-six dollars now and fifty dollars a month regularly."The manager got up and opened the door. He called to the accountant."Mr. Montgomery," he said unkindly loud, "this gentleman is opening an account; he will deposit fifty-six dollars. Good morning."I rose. A big iron door stood open at the side of the room."Good morning," I said, and stepped into the safe."Come out," said the manager coldly, and showed me the other way.I went up to the accountant's wicket and poked the ball of money at him with a quick convulsive movement as if I were doing a conjuring trick.My face was ghastly pale."Here," I said, "deposit it." The tone of the words seemed to mean, "Let us do this painful thing while the fit is on us."He took the money and gave it to another clerk. He made me write the sum on a slip and sign my name in a book. I no longer knew what I was doing. The bank swam before my eyes."Is it deposited?" I asked in a hollow, vibrating voice."It is," said the accountant."Then I want to draw a cheque."My idea was to draw out six dollars of it for present use. Someone gave me a chequebook through a wicket, and someone else began telling me how to write it out. The people in the bank had the impression that I was an invalid millionaire. I wrote something on the check and thrust it in at the clerk. He looked at it."What! are you drawing it all out again?" he asked in surprise.Then I realized that I had written fifty-six instead of six. I was too far gone to reason now. I had a feeling that it was impossible to explain the thing. All the clerks had stopped writing to look at me.Reckless with misery, I made a plunge."Yes, the whole thing.""You withdraw your money from the bank?""Every cent of it.""Are you not going to deposit any more?" said the clerk, astonished."Never."An idiot hope struck me that they might think something had insulted me while I was writing the cheque and that I had changed my mind. I made a wretched attempt to look like a man with a fearfully quick temper.The clerk prepared to pay the money."How will you have it?" he said."What?""How will you have it?""Oh" I caught his meaning and answered without even trying to think "in fifties."He gave me a fifty-dollar bill."And the six?" he asked dryly."In sixes," I said.He gave it to me and I rushed out. As the big door swung behind me, I caught the echo of a roar of laughter that went up to the ceiling of the bank. Since then I bank no more. I keep my money in cash in my trousers pocket and my savings in silver dollars in a sock.
