-5n+4n-7=8
What is the answer for n and how do you solve it

Answers

Answer:

-15

Step-by-step explanation:

First combine like terms, aka the variables

-5n+4n-7=8

-1n-7=8

Then, isolate the variable by adding 7 to both sides

-1n-7+7=8+7

-1n=15

Finally, solve by dividing both sides by -1

-1n/-1=15/-1

n=-15

Answer:

n = -15

Step-by-step explanation:

I'll try my best to explain how I solved this

Equation:

-5n + 4n -7=8

Add the light terms on each side:

-n -7 =8

Separate the variables from the numbers:

-n = 15

Do the operation necessary to solve it:

n = -15

x+8 = 15 + 4x - 7

How many solutions are there

Answers

Answer:

One Solution: 0

Step-by-step explanation:

Step 1:

x + 8 = 15 + 4x - 7       Equation

Step 2:

8 = 15 + 3x - 7       Subtract x on both sides

Step 3:

8 = 8 + 3x         Combine Like Terms

Step 4:

0 = 3x       Subtract 8 on both sides

Answer:

x = 0

Answer:

Removing the -6 makes the average go from 4.1 to 5.2

Removing the -6 makes the median go from 4 to 5

Step-by-step explanation:

Average:

-6+3+3+3+3+5+6+6+8+10 = 41

41/10 = 4.1 (This is the mean/average)

If we remove -6, then:

3+3+3+3+5+6+6+8+10 = 47

47/9 = 5.2222 (This would be the new average)

So removing the -6 makes the average go from 4.1 to 5.2

Median:

The median of (-6+3+3+3+3+5+6+6+8+10) is between 3 and 5, so the median is 4.

Without -6, the median of (3+3+3+3+5+6+6+8+10) is 5.

So removing the -6 makes the median go from 4 to 5
