5/9
5 times 4= 20
12 times 3=36
20/36=5/9
X = premium seats
y = regular seats
You need two equations: (x + y - 10 = 1200) and (30x + 20y = 30,180)
1.) Isolate one variable
y = 1,210 - x
2.) Plug the new equation into the second ORIGINAL equation
30x +20(1,210 - x) = 30,180
3.) Ditribute
30x + 24,200 - 20x = 30,180
4.) Add like terms
10x + 24,200 = 30,180
5.) Subtract 24,000 from either side
10x = 6,180
6.) Solve for x
x = 618
7.) Plug in x to the equation of your choosing
618 + y - 10 = 1200
8.) Solve for y
608 + y = 1,200
y = 592
The theater sold 592 regular seats and 618 premium seats.
The answer would be D, because you do 4200÷56=75 minutes. 75 minutes= 1 hour and 15 minutes
Bills right because the y-intercept is 50 so I’m think what he’s saying about the rocket being launched 50 feet above water is right
D is the answer because all you have to do is solve
