x = # of balcony seats
y = # of orchestra seats
We have to create a system of equations to solve this problem
x + y = 256
$8x + $12y = $2,716
We will solve this system of equations by elimination.
Multiply the first equation by -8
-8x - 8y = -2048
8x + 12y = 2716
Let's add the equations together
0 + 4y = 668
Simplify the left side
4y = 668
Divide both sides by 4
y = 167
We can subtract 167 from 257 to get the number of balcony seats.
257 - 167 = 90 balcony seats
There are 167 orchestra seats and 90 balcony seats

Answer:
C)
Step-by-step explanation:
As it is 60 degree, and the whole circle is 360 degree, so we need to find 1/6 of the circumference of a circle, as C = 2*pi*r = 2*pi*3 = 6pi and 1/6 of it is pi.
Answer:
Polynomial is the general term, but some polynomials can be classified in a more specific way.
Step-by-step explanation:
This is exactly how Polynomials work: Polynomial is the general term, but some polynomials can be classified in a more specific way. A polynomial is any sum (or difference) of terms. A term is separated by a plus or minus sign (that's why the word sum is used). Some polynomials can be classified more specifically as monomials, binomials, or trinomials.
