Answer:
9 comedy
12 horror
Step-by-step explanation:
First, there are 360 degrees in a circle.
Comedy = 90 degrees
Action and romance = 90 degrees combined
Horror = 120 degree
Science fiction = 60 degrees
To find sci fi : 90 +90 +120 = 300 - 360 = 60 degrees
36 students took the survey.
1/4 × 36 = 9
Horror is 120 degrees out of 360 degrees or 1/3 of the circle.
1/3 × 36 = 12
multiply the top equation by 3, multiply the bottom equation by 4, then subtract the bottom equation from the top equation
multiply the top equation by 3, multiply the bottom equation by -2, then add the equations
19/5=p/3-36/5
Convert the decimals into fractions
15 x 19/5=(p/3-36/5) x 15
Multiply both sides by 15
57=5x-108
5x-108+108=57+108
Add 108 to both sides
5x=165
X=33

Hope this helps
Q(3) = -2(3)+2 = -4
r(q(3)) = (-4)^2-1 = 15
Easy, 100 x 3 is 300 pounds, 5 x 3 is 15, so 15 pounds. :)
