Answer:

x=8

Step-by-step explanation:

3*8=24 24+2=26 26/2=13

Answer:

x = 8

Step-by-step explanation:

First, you'll need to times 13 with 2 which would equal 26, then from there, takeaway 2 which gives you the number of 24. After that, we know that 3x is equal to 24, so we simply need to divide it by 3, which gives you 8!

Maria is planning a party for her friends. Sally's Kitchen charges a fee of

$60 to set up and then $12 per plate. Jimmy's BBQ and Steak charges a fee

of $100 to set up and then $10 per plate. At how many plates will the cost

of Sally's and Jimmy's be the same? How many plates will the cost of

Sally's and Jimmy's be the same? *

Answers

Answer:

20 Plates

Step-by-step explanation:

Given that :

Sally's kitchen :

Setup cost = $60

Cost per plate = $12

Jimmy's BBQ :

Setup cost = $100

Cost per plate = $10

Let number of plates = x

Equate both and solve for x :

Sally's kitchen = Jimmy's BBQ

60 + 12x = 100 + 10x

12x - 10x = 100 - 60

2x = 40

x = 40/2

x = 20

20 plates

Answer:

-2x

Step-by-step explanation:

x - 3x is = -2x (i got this from the left side of the equation)

and you need both sides of the equation to be equal to each other for it to be infinite number of solutions. since -2x is the same as x - 3x and both sides of the equations have +15, then you need to find the value that would make the equations the same. and -2x is that

Answer: Its 82 im pretty sure you just needed to do area and multiply it

Step-by-step explanation: I just multiplied.

It is 168.
This happens because
9 x 12 = 108.
Then you would have to multiply 4 by 15 and get 60.
Next you add 108 with 60, and get 168.

Remember,after multiplying nine by twelve and get 108, you have to divide by two. Then since there are two sides in the triangle you multiply by two and get 108.

In other words your answer is 168

A nonagon had nine sides and the interiors angles equal 1260 degrees. X is on of those interior angles. So 1260/9 equals 140.
X =140
the answer above is correct, however, if you are seeing more of these questions in the future and don't know how to do it. you take the amount of sides (9) - 2 to get 7. Then multiply by 180 to get 1260. 1260/9 is 140

Valorie made five times more baskets than her brother, Vance.

The equation v = 5n, where v represents the number of baskets Valorie made, and n represents the number of baskets Vance made, shows this relationship.

If Valorie made 55 baskets, how many baskets did Vance make?
A.
8
B.
11
C.
50
D.
60

Answers

Answer:

B. 11

Step-by-step explanation:

Valorie made five times more baskets, so if you replace the V in the equation with how many baskets she made (55), it would look like 55=5n. Divide 55 and the n by five to get rid the five in the equation. 11=n. Thus, the answer is B.

She raised her hand, and made a slight, quick movement toward the right. No one but her lover saw her. Every eye but his was fixed on the man in the arena.He turned, and with a firm and rapid step he walked across the empty space. Every heart stopped beating, every breath was held, every eye was fixed immovably upon that man. Without the slightest hesitation, he went to the door on the right, and opened it.Behind it, to the surprise of the youth, was a small wooden platform on a pole. The fine lady high in the air on the platform, with the tiger circling it, trying to find a way up to her.He was very confused. Was this new? He assumed he had to try and save her. Why did his lover direct him to this door? Unless the other door held a worse fate. He knew he did not have much time, the tiger had not noticed him yet. How was he going to get up to her? Then he saw a plank of wood in the corner of the dungeon, just long enough to reach her. But to get to the plank he would have to pass the tiger, which was sure to notice him.There was no other way, he had to run for it to the plank. He bilt up all of the courage he had, and sprinted for the piece of wood. The tiger had spotted the youth as he predicted but he did not look back. He got to the wood plank and grabbed it. Just then he heard the tiger feet behind him. With one swift movement he turned and hit the tiger full in the face with the piece of wood. With the tiger temporarily dazed he ran for the beautiful lady on the platform, set the plank up, grabbed her hand, and ran as fast as he can for the door out of the dungeon and to fresh air.The tiger, now recovered, was right behind them. The youth new the tiger would cach them soon, but they were so close. The door was right in front of them. The youth and the lady both jumped out of the dungeon and closed the door hard on the tiger. They were met with great applause. The youth looked up at his lover, and smiled, and she smiled back.2. ...Her right arm lay on the cushioned parapet before her. She raised her hand, and made a slight, quick movement toward the right. Her father, the king however, saw this slight movement of his daughter's hand. He could not believe that she could love such a man. This youth knew quite well that he was not at no circumstances allowed to be with his daughter.The more the king thought about it, the more angrier he became. The youth was halfway to the door when he shouted out; Wait! Everybody, pulse, his daughter looks at his majesty. The king continued; I think, for the crime of loving my daughter, which he fully knew he was not permitted to do. He is not allowed to have a trial of chance.The youth was standing in the arena, obviously not knowing where the king was taking this.
