All possibilities = 9!
possibilities that harry sits at an end = 8! + 8!
possibilities that harry doesn't sit at an end = 9! - 8! -8!
Average must be 225 or more
4 games so

score1=192
score2=214
score3=250
score4=?
so


times both sides by 4 to clear fraction
656+?≥900
minus 656 from both sides
?≥244
min score is 244
Answer:
The answer should be y ≤ 1/3x - 1 I believe
Answer:
y=5/7 x=31/7
Step-by-step explanation:
Make the x values the opposite of each other:
-2(x+5y=8)
-2x-10y=-16
2x+3y=9
Combine like terms and solve for y:
-7y=-5
y=5/7
Plug y in to find x.
x+5(5/7)=8
x+25/7=8
56/7-25/7=x
x=31/7
