MAE - 48 = 36 x 2
mAE - 48 = 72
mAE = 120
Answer
120
Answer:
9
Step-by-step explanation:
5,7,8,10,12,12
5+7+8+10+12+12=54
54/(how many numbers there are, which is 6)=9.
Your mean value is 9.
Y = -6x + 2 . . . . . . . . (1)
-12x - 2y = -4 . . . . . . (2)
Putting (1) into (2), we have
-12x - 2(-6x + 2) = -4
-12x + 12x - 4 = -4
-4 = -4
Therefore, the system has infinite number of solutions.
-15 because there is ten before 25
Consecutive terms in an arithmetic sequence differ by a constant

. So



Denote the

-th term in the sequence by

. Now that

, we have

which means
