Answer:
5 : 18 : 12
Step-by-step explanation:
Express the ratio B : C in fractional form, that is
= 
( cross- multiply )
6C = 4B ( divide both sides by 6 )
C = 
B = 
B , then
C = × 18 = 2 × 6 = 12
Hence
A : B : C = 5 : 18 : 12
Alright this is gonna be a long one
Lets called child tickets x and adult tickets y
so x + y should be equal to 159 since they said that the total sum of the tickets is 159
so thats your first equation : x + y = 159
next form an equation using the prices,
5.40x + 8.70y = 1079.70
now that you have your two equations, just substitute the first into the second (you could either substitute for x or y by saying x = 159-y or that y=159-x)
Hope this helps.

Answer:
b = (d-c)/a
Step-by-step explanation:
ab+c=d
Subtract c from each side
ab+c-c=d-c
ab = d-c
Divide by a
ab/a = (d-c)/a
b = (d-c)/a
