Answer:
-5,3
Step-by-step explanation:
Hey there!!
Let's take the two numbers as 'x' and 'y'
The sum of these two numbers is 36.
... x + y = 36
Twice the first number minus the second is 6.
... 2x - y = 6
Now, we have two equations.
_______________________________________________________
... x + y = 36
... 2x - y = 6
Now, let's add both the equations.
... 3x = 42
Divide each side by 3.
... x = 42 / 3
... x = 14
<em>Hence, the first number is'14'. </em>
We know the sum of both the numbers is 36.
... x + y = 36
... 14 + y = 36
Subtract 14 on both sides.
... y = 36-14
... y = 22
<em>Hence, the second number is 22. </em>
<em>The numbers are 14 and 22. </em>
Hope my answer helps!!
To find the mean you add up all the numbers and divide that amount by the amount of numbers. Which looks like this:
7 + 20 + 8 + 15 + 10 + 17 + 7 + 13= 97
97 divided by 8 = 12.125
The mean is 12.125.
To find the median you first need to put the numbers in order and then try to find the number in the middle. If there is two numbers in the middle those two numbers are still the median:
7, 7, 8, 10, 13, 15, 17, 20,
The median(s) are 10 and 13.
