Find the value of x<br>9.10.12,x, 20.25 ; The median is 14.​
Elodia [21]

Answer: 16  

Step-by-step explanation:

9,10,12,x ,20, 25  so we know the median is 14 which is the middle number.

Since the numbers are 6 it means there will be 2 middle numbers and if you divide them it will be 14.

we know one of the middle numbers is 12 and we trying to find x .

So we could use the equation x  + 12 = 2(14)

                                                  x + 12 = 28

                                                     -12   -12  

                                                x= 16  so X is 16.       check:  16+12=28/2 is 14.

Don’t really understand it someone help

Answer:

<em>n = 8 or n = −2</em> <em>is the correction solution.</em>

Step-by-step explanation:

As the absolute value equation is given:                                      

                                            | n−3 | = 5

We know either n − 3 = 5 or n − 3 = −5

                                               n − 3 = 5            (First Possibility)

                                          n − 3 + 3 = 5 + 3

                                                       n = 8

                                                n − 3 = -5            (Second Possibility)

                                                      n = -5 + 3

                                                      n = -2

                  <em> So, n = 8 or n = −2</em> <em>is the correction solution.</em>
