Answer:
18
Step-by-step explanation:
The average is found by adding all the numbers and dividing by 5
(2+ 81+ 29+ 18+ x)/5 = 26.8
Multiply each side by 5
(2+ 81+ 29+ 18+ x) = 134
x+130 =134
Subtract 130 from each side
x = 4
Now we want the median
List the numbers in order from smallest to largest
2,4,18,29 ,81
The median is the middle
Divide:
a.) 5,600/20 = 280
b.) 475/25 = 19
c.) 650/50 = 13
d.) 7,280/80 = 91

Answer:
17n+9 feet
Step-by-step explanation:
The perimeter of a rectangle is twice the sum of length and width.
P = 2(L +W)
P = 2((4.5n +9) +(4n -4.5)) = 2(8.5n +4.5)
P = 17n +9
The perimeter of the rectangle is 17n +9 feet.
