A - 3b = 4
a = b -2
(b - 2) - 3b = 4
b - 2 - 3b = 4
-2b = 4 + 2
-2b = 6
b = 6/-2
b = -3
a = b - 2
a = -3 -2
a = -5
to check: a = -5 ; b = -3 ⇒ (-5,-3)
a - 3b = 4
-5 - 3(-3) = 4
-5 + 9 = 4
4 = 4
Answer: G=A, D=H, E=F, and B=C.

Step-by-step explanation:
2) 8,6,5,3 ,57 7,4,2/8
=92/8
mean =11.5
Arrange the terms in ascending order
2,3, 4, 5, 6, 7, 8, 57
the median of the ascending set= 5.5
3) 72 75 85 82 37 108/ 6
459/6
mean =76.5
Arrange the terms in ascending order
37, 72, 75, 82, 85, 108
the median of the ascending set= 78.5
4) 10 students were asked because there were 10 data values in the list.
5) it should be 55/10 =5.5
so its false
