ok so i take the 2nd part of m final tomarow in math and i blew the first part so i need to get an A on second. so, i need help with somethings on the review to answer so i can study, person who helps most get 10 points so plz?
What is median?
Solve for x: 2.4x=14.4
Solve for x: x+9/10=1/4
How do you do peremiter and area and a good way to memorize it?
i have more but there like hard to put in the question so answer those please and thanks you :D

What is median?
---------------------------
The median of a sorted collection of data is the middle element, and when there are an even number of elements in the collection, it's the mean of the two middle elements. e.g.
[76, 65, 54, 87, 34, 65]
sort it....
[34, 54, 65, 65, 76, 87]
even number of items, take mean of middle two....
(65 + 65)/2 = 65
---------------------------
Solve for x: 2.4x=14.4
---------------------------
Get x all by itself. Divide both sides by the constant factor of x, 2.4. Remember that whatever you do to one side you must do to the other.
(2.4*x)/2.4 = 14.4/2.4
x = 6
---------------------------
Solve for x: x+9/10=1/4
---------------------------
Again, get x by itself. Subtract 9/10 from both sides.
x + 9/10 - 9/10 = 1/4 - 9/10
Find the LCM (Least Common Multiple) of the denominators (4 and 10) to subtract 1/4 and 9/10: it's 20
x + 9/10 - 9/10 = 5/20 - 18/20
x = -13/20

The median is the middle number
Divide both sides by 2.4
subtract 9/10 from both sides, but convert both to the same denominator
The factors of 10 are 2 and 5............factors of 4 are 2 and 2........so the lowest common multiple is 2 *2 * 5 or 20 ...........simple rule is ..........each prime number used, the most number of times, it occurs
Divide both sides by 2.4
subtract 9/10 from both sides, but convert both to the same denominator
