Answer:
9:12
Step-by-step explanation:
since the others are multiples of 2:3
but 9:12 is not a multiple
Substitute y = 4x - 1 in the first equation:-
4x - 1 = 8x - 9
-4x = -8
x = 2
Now substitute x = 2 in the second equation:-
y = 4(2) - 1 = 7
Solution is (2, 7). (That is y = 7 and x = 2)
Part B
The graphs will intersect at the point (2, 7)

Have a great day:)
Mean simply means average
so just add them all up and divide by 5
22 + 37 + 49 + 15 + 71 = 195
195/5 = 39
mean = 39
