Well, we know that Lilly scored 4 more points than Bryson. So we could write that
<span>Lilly's score = Bryson's score plus 4. Or L=B+4 Now we also know that </span>
<span>Lilly's score + Bryson's score = 180. So L+B=180 Now We can substitute in L in the second equation to get B+B+4=180 so B+B=176 and B=88 The we put B into the first equation and find that </span>
<span>L=92.</span>

just substitute -8 for all x
process here:
f(x) = -3x + 7
f(-8)= -3(-8) + 7
Answer: 13
Step-by-step explanation:
If you remember the quadratic equation formula;

You can easily extract what is under the root to find the discriminant.

a = 3
b = 7
c = 3

Consider the number of the adult tickets is x
X+2x=276
3x=276
X=92
So the student tickets is =184
