I’m confused can someone explain?
Novay_Z [31]

Answer:

It is 150 percent

Step-by-step explanation:

You can find this value by dividing the numerator by the denominator, summing this value to the integer part and multiplying the result by 100%, so:

1 1/2 in percent = (1 + 1/2) × 100% =

(1 + 0.5) × 100% = 1.5 × 100% = 150%

Hope this helps! Sorry if I'm wrong.

8-6x>-18 solve for x
EleoNora [17]

Answer:

x=5

Step-by-step explanation:

Well all i did was guess a random number from 1-10 so I could see what numbers make the equation bigger than -18 and the fist thing I guessed was 5 so this is what I did

8-6*5=-22

And them I said let me see if any multiples equal -18 so I went to for and did this

8-6*4=-16

That's when I guessed the answer if i looked at the sign correctly!

Don't neglect the “easy” stuff.

1. Start Studying in School

Studying for tests and quizzes actually starts way before you even know you'll have a test. Good study techniques begin in the classroom as you take notes. Note-taking is a way of remembering what you were taught or what you've read about.

Some keys to note-taking are to write down facts that a teacher mentions or writes on the board during class. If you miss something, ask your teacher to go over the facts with you after class.

Keep your notes organized by subject and making sure they're easy to read and review. This may mean that you need to recopy some notes at home or during a free period while the class is still fresh in your mind.

Unfortunately, most schools don't have classes that teach you how to take notes. When it comes to taking good notes, it can take some experimenting to figure out what works, so don't give up.

2. Plan Your Study Time

When you sit down to study, think about how much time you want to devote to each topic. This will keep you from getting overwhelmed.

If it's Monday, and you've got three tests on Friday, figure out how much time you need for studying between now and then. Then figure out how long each subject will take. For example, a weekly Spanish verb test probably won't be as intense as a big history test. So you won't need to set aside as much study time for the Spanish test — and if you break it up into a short amount every night, that's even better.

Another study technique is called "chunking" — breaking large topics down into chunks. Let's say you have a history test on World War II. Instead of thinking about studying all of World War II (which could overwhelm even an expert), try breaking your study sessions into 2-year chunks or studying the material by specific battles.

Most people can concentrate well for about 45 minutes. After that you'll probably want to take a short break. If you find yourself getting distracted and thinking about other things as you study, pull your attention back. Remind yourself that when your 45 minutes of studying are up, you can take a 15-minute break.

3. Study Based on the Type of Test You're Taking

Many teachers tell students ahead of time what the format of an exam will be. This can help you tailor how you study. For example, if you know you're going to have multiple-choice questions on World War II, you'll know to focus on studying facts and details. But if the exam will contain essay questions, you'll want to think about which topics are most likely to be covered. Then come up with several possible essay topics and use your notes, books, and other reference sources to figure out how you might answer questions on those topics.

As you study, review your notes and any special information from your textbook. Read things over several times if you need to, and write down any phrases or thoughts that will help you remember main ideas or concepts.

When trying to memorize dates, names, or other factual information, keep in mind that it usually takes a number of tries to remember something correctly. That's one reason why it's a good idea to start studying well in advance of a test. Use special memory triggers that the teacher may have suggested or ones that you invent yourself.

In the case of math or science problems or equations, do some practice problems. Pay special attention to anything the teacher seemed to stress in class. (This is where good note-taking comes in handy!)

Some people find it helps to teach what they're studying aloud to an imaginary student. Or work with a study partner and take turns teaching aloud. Another study technique is making flashcards that summarize some of the important facts or concepts. You can then use these to review for a test.
