X represents the amount of children's tickets
y represents the amount of adult's tickets
8(x+y) = 54
4/8-3/8=1/8more
Therefore Keith at 1/8 more of the sandwich than Henry.
First you must distribute the 1/4 to get
: 1/2x^2-3=15
then you have to add three to both sides so it become
: 1/2x^2=18
then divide by 1/2 to get
:x^2 =36
then take the square root to get a final answer of
:x=6
Plug in 0 into x of the equation y=2x+3, solve it, then take that answer and use that as your y then plug in the answer for y and solve for x. (i realized i am very bad at explaining this over this. Sorry I tried)
