okay im not sure but maybe try to find a number that can be = to 18 and that might be y
Answer:
23
Step-by-step explanation:
The amount of children's tickets is x, while the amount of adults' tickets is 2x
5.1*x- the amount of money from children
9.6*2x= 19.2x- the amount of money from adults
5.1x+19.2x= 558.9
x=23 - child tickets
14:10 Multiply both numbers by the same value to find equivalent ratios
the answer is b (-4+6)/2&(-4-6)/2
