Answer:
11
Step-by-step explanation:
first, sort the numbers from lowest to highest.
5,5,6,7,8,9,10,*10,12*,14,15,17,18,18,18,20
the median is the number in the middle of the data
average if you need to (10+12 and divide by 2)
x = -8/b
2bx-bx= -8
bx = -8
Divide by b since b is nonzero
B
because 4 and 3 are grouped together you would add them first. this would change the outcome of the problem.
30
60/40=3/2
105/40+x = 3/2
105/70=3/2
x=70-40 = 30
