Represent this statement as an equation: The difference of twice a number and 3 is 11.

Answers

Answer:

2x - 3 = 11

Step-by-step explanation:

"difference" means subtraction, so it is subtraction.

"twice a number" simply means 2x, since you do not know what the specified number is, it is x. and the 2 and just making it twice the number.

"Is 11" just means equals 11.

Step-by-step explanation:

Tanya bought three adult tickets and one children's ticket to a movie for 24.60 Li bought five adult tickets and four children's tickets for 50.10 . Find the cost of one adult ticket and the cost of one children's ticket.

Answers

Answer:

adult tickets  6.9

children tickets  3.9

Step-by-step explanation:

3x + y = 24.60    L1

5x + 4y = 50.10  L2

5L1 - 3L2

15x +  5y = 123

-15x - 12y = -150.3

-7y = -27,3

y = -27,3/-7

y = 3.9

3x + y = 24.60

3x + 3.9 = 24.60

3x = 24.60 - 3.9

3x = 20.7

x = 20.7 / 3

x = 6.9

Is the atmosphere a open or closed system? I did a Spanish project where I have to write as if I'm writing in a diary (journaling) about 3 fun adventures, and I need someone to check my Spanish. My project is super short, it won't take long to look over. Please tell me anything that I can do to improve my Spanish and anything I need to correct. Here are the rules for the project: Write one general sentence stating that the weather is good, bad, beautiful, etc. Write two specific types of weather, such as sunny, cloudy, cold, hot, mild, raining, snowing, foggy, drizzling, etc. Write the temperature. Description of the place: Using the Spanish you've studied so far, describe the appearance of the location by using the correct form of ser with descriptive adjectives. Use hay, meaning "there is" or "there are" to talk about things that are found there. This description should include at least three pieces of information about the location. Account of the day's events: Choose three activities per picture. All activities should be in the present tense, since the past tense hasn't been studied in detail. However, with teacher permission, the past tense charts in lesson 1 may be used to tell about specific activities that were done that day. Use of Spanish in the writing: Make sure that the verb endings match their subjects. Check that all irregular verbs are spelled correctly. Verify that the overall communication is clear and knowledge acquired from the program was clearly applied in your writing. Make sure that a variety of weather vocabulary is used and there isn't much repetition of the same weather conditions from one picture to the next. Pictures to include: Include a picture of each of the three locations you reference in your project. These pictures should represent the weather and places you describe in Spanish. Te toca a ti. It's time to get started! This project may be completed as a journal on paper, but can also be a slide show, or any other creative presentation you can think of. It's best to follow the simple steps below to work through it. Part 1: Your pictures are the main focus, so begin your project by choosing three pictures that show interesting things, and a variety of weather conditions. For instance, you can use pictures of a ski resort when it's snowing, an adventure park when its raining and the lines for the rides are very short, and a park or beach when the weather is sunny. Decide how you'd like to put your information together. Choose whether you'll create a journal, a slide show presentation, or some other way to bring your information together. Make notes on the weather, descriptions, and activities you plan to discuss in the project. Write your paragraphs in Spanish and have your teacher or a peer edit your work and give you suggestions for improvement if necessary. Create a rough draft of your journal with writing and pictures all in place. Edit your work, and make sure verbs are conjugated correctly, adjectives agree with the nouns they modify, and weather expressions are used correctly. Ask somebody who understands Spanish to edit your work again. Make any changes necessary and then check your work thoroughly for both content and appearance. If your teacher requires you to present the project, tell your classmates all about your vacation and have fun! 100 points Write a function g whose graph represents the indicated transformation of the graph of f. f(x) = (1/2)x - 5; reflection in the x-axis a g(x) = (1/2)x - 5 b g(x) = -(1/2)x + 5 c none d g(x) = -(1/2)x - 5 e g(x) = (1/2)x + 5 6.
