The Celluloid Cinema sold 150 tickets to a movie. Some of these were child tickets and the rest were adult tickets. A child ticket cost $7.75
and an adult ticket cost $10.25. If the cinema sold $1470 worth
of tickets, which system of equations could be used to determine
how many adult tickets, a, and how many child tickets, c, were sold?
(1) a te - 150
(3) a te - 150
10.25a + 7.750 = 1470 7.75a + 10.250 = 1470
(2) a + 1470
(4) ate 1470
10.25a + 7.750 = 150
7.750 + 10.250 = 150

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
