Answer:
10-x
Step-by-step explanation:
The total amount is made up of movies and music
total = movies + music
10 = x+ music
Subtract x from each side
10-x = x+music-x
10-x = music
Answer:
Step-by-step explanation:
given that the U.S. Department of Housing and Urban Development (HUD) uses the median to report the average price of a home in the United States.
We know that mean, median and mode are measures of central tendency.
Mean is the average of all the prices while median is the middle entry when arranged in ascending order.
Mean has the disadvantage of showing undue figure if extreme entries are there. i.e. outlier affect mean.
Suppose a price goes extremely high, then mean will fluctuate more than median.
So median using gives a reliable estimate since median gives the middle price and equally spread to other sides.

Answer: The width is 
+ 1x -4
Step-by-step explanation:
We know to find the perimeter we have to add the distance around the rectangle.The distance can also be sought as 2 times the length plus times the width.
So as a formula is like P = 2l + 2w where P is the perimeter.
We are given the perimeter so we can plot it into the formula and also plot in the length because it says the length is 3x -1
+8x - 10 = 2(3x -1) + 2w Now we have to solve for w .Break it down
( + 8x -10) = (6x -2 )+ 2w subtract 6x - 2 from both sides
( + 8x -10) - (6x -2) = 2w
( + 2x -8) = 2w now divide both sides by 2
One the left side factor the numerator
= w Now multiply both sides by 2
w =( + 1x-4 )
The width is x^2 + 1x -4
There are four pairs (m,n) that work: (5,10), (6,6), (8,4), and (12,3).
