X = number of students who are members.
<span>19-x is the number of people who are not members.</span> x number of people paid $11 for tickets and (19-x) number of people paid $13.$11x+$13(19-x)=$209 for the total cost of the tickets.
$11x+ $247-$13x=$209 $11x-13x = $209 - $247
$-2x = $-38
divide -2 by both sides
x=19, meaning that all of the students are members.
Answer:
-5 , -3 , 0 , 4 , 5

Negative numbers are always less than positive numbers.
255 is the best answer because 36 x 7 = 252 + 3 = 255 ... I tried to make that as short as can be
180-(92+86)
Since it's a triangle the sum of all angles is 180. So 180-86-92=2
