Answer:

x= 14

Step-by-step explanation:

First, lets take the L.C.M on one side, so that it becomes a little more unified.

=> 9= X/2 + 4/2

now, lets shift the 2 to the L.H.S to make it even simpler.

=> 18= x+4

Now, lets move 4 to the L.H.S, to subtract it from 18.

=> 14= x

Thus, x=14

the midpoint of AB is point P at (-16,6) if point A is at (-10,8) what are the coordinates of point B?

max2010maxim [7]

Answer:

Denote B(x, y), we have:

-10 + x = 2 x (-16) => x = -22

8 + y = 2 x 6 => y = 4

=> B(-22, 4)

What is the median of this set of data: 593, 588, 540, 434, 420, 398, 390, 375

Aleks04 [339]

Answer:

426

Explanation:

To find the median number in a set of data start by reordering the data from least to greatest.

original data set:

593, 588, 540, 434, 420, 398, 390, 375

data set from least to greatest:

375, 390, 398, 420, 434, 540, 588, 593

Next, you would usually just have to find the middle number in the data set and that would be your median. However, this data set has no one number that is directly in the middle. So, we will add both middle numbers together and then divide our answer by two.

375, 390, 398, 420, 434, 540, 588, 593

420 + 434 = 854

854 ÷ 2 = 426

Therefore, the median of the given data set is 426.

#6 math help fun please?

julsineya [31]

Answer:

mean: 27.6

median: 32

mode: 35

range: 35

Step-by-step explanation:

Definitions:

mean: average

median: middle

mode: the number that comes up the most

range: the difference between the highest and lowest values/numbers

What to do:

mean: you add up all the numbers and then you divide that sum by the amount of numbers there are (I'm not going to do the work because that's a lot of numbers to type out, but you can check your work with my answer).

~answer is 27.6

median: middle number --> 32

mode: the number that comes up the most --> 35

range: 40-5 = 35
