Answer:
8
Step-by-step explanation:
( 12 + 3m ) / 2 = 18
12 + 3m = 18 x 2
12 + 3m = 36
3m = 36 - 12
3m = 24
m = 24 / 3
m = 8
Answer:
r=20
Step-by-step explanation:

Answer:
a
Step-by-step explanation:
the median is the middle value of the data arranged in ascending order
5 , 6 , 6 , 7 , 8 , 10 , 12 , 13 , 14 ← ascending order
↑ middle value
median = 8
The equation to solve this would be:
-4+x=25
Solve for x.
Add 4 to both sides.
(-4+x)+4=(25)+4
x=29
The overall change to account was $29.
Hope this helps.
