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:give her brainlist she is right
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
the frequency will change for each trial so a is wrong
b yea the probability should increase for either head or tail as the experiment progresses
c it will be impossible to get the frequency of head to equal the frequency of tails
d this is a 49/51 chance depending on what side did it flip on so while the frequency could increase the frequency could also decrease
the answer is B
I'm from your other question asking for help lmæo. and besides who flips that many coins
Answer:
No. It is not. The opposite is -5
Step-by-step explanation:
I -5 I
The symbols; | | represents absolute value.
It gives the non negative value of that number irrespective of the sign of the number.
That is;
| -a | = a and | a | = a
So in this case;
| -5 | = 5
Opposite of 5 = -5
So the answer is FALSE!
