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.

Answer:
Option 1: 1430p + 2200 = -4001
Step-by-step explanation:
Given that:
1.43p + 2.2 = -4.001
We can replace:
1.43p by 1430p * 10^-3
2.2 by 2200 * 10^-3
-4.001 by -4001* 10^-3
So the equation will become:
1430p * 10^-3 + 2200* 10^-3 = -4001 * 10^-3
Taking 10^-3 common from both side
(1430p + 2200)* 10^-3 = -4001 * 10^-3
Cancelling 10^-3 from both sides we get:
1430p + 2200 = -4001
I think it's B. because 4,310 divided by 72 is about 59. And 4,200 divided by 70 is 60.
Answer:
1 inch does equal 2.54
Formula = multiply the length value by 2.54
The answer is 25.4 cm
