3x+2(3x-3)=2
9x-6=2
9x=8
X=8/9
Answer:
n=9
Step-by-step explanation:
-5-4n=-41
+5 +5
---------------
-4n=-36
---------------
-4n/4=-36/-4
---------------
n=9
X=the missing value
the median is the middle number, but in this case there are two which happens to be 25 and x
so the formula is
25+x/2=31.5
use algebra to solve
25+x=63
x=63-25
x= 38
Therefore, the missing value is 38.
