The answer is 210 children tickets were sold . if you multiply the first equation by 7 it would be 7x+7y=2590. then subtract equation 2 from 1 you will have 4x=840 so x=210. Also you can use substitution method.
H= -8. H-2h= 9-1; -h=8; h= -8
It would be 11.25 inches because 1800 divided by 160 is 11.25
