Find the solution to the equation.

n + 13 = 52

Answers

Answer:

N = 39

Step-by-step explanation:

N + 13 = 52

-13. -13

N = 39

Answer:

n = 39

Step-by-step explanation:

To find what n equals, I want to get it alone on one side of the equation.

To do this, I move 13 to the right side of the equation by subtracting 13 from both sides.

13-13=0 so n is the only value on the left side

52-13=39.

You are now left with n = 39

To check that this is right, add 13 to 39. It equals 52, so you know the answer you found is correct.

The Martinez Family has driven 240 miles so far. Their total trip is 300 miles. What percentage of the trip have they already driven?

Answers

Answer:

80%

Step-by-step explanation:

Percentage of the trip covered = [tex]\frac{miles driven }{total miles}[/tex] × 100

I am multiplying by 100 because to convert to percentage, we have to multiply by 100

Miles drive = 240

Total miles = 300

[tex]\frac{240}{300}[/tex] × 100 = 80%

Answers

Answer:

-5n-6n< 8-8n-n

-11n < -9n + 8

-2n < 8

n > -4

Answer:

n>-4

Step-by-step explanation:

Let's solve your inequality step-by-step.

−5n−6n<8−8n−n

Step 1: Simplify both sides of the inequality.

−11n<−9n+8

Step 2: Add 9n to both sides.

−11n+9n<−9n+8+9n

−2n<8

Step 3: Divide both sides by -2.

What is the slope of the line that passes through M(-6, 1) and N(2, 5)?

Answers

Answer:

m = 1/2

Step-by-step explanation:

As we move from M to N, the x-coordinate increases from -6 to 2, a jump ('run') of 8 units.  Likewise, the y-coordinate increases from 1 to 5, a jump of 4 units.  The slope of the line passing through these two points is thus

m = rise / run = 4/8 = 1/2

THE LONG PART IS JUST THE STORY. PLEASE HURRY Memories of a MemoryHave you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed.
