STV=STU+UTV
But,
STV=90° and STU = 75°
Therefore,
90=75+UTV => UTV = 90-75
Therefore, expression A is the one that can be used to find UTV.

Answer:
<h2>(4x+z)=13000------1</h2><h2>(4x+z)13000=503000----2</h2>
Step-by-step explanation:
let x be the number of seats in A,
y be the number of seats in B, and
z be the number of lawn seats.
y=3x
the total number of seats is given by
(x+y+z)=13000
put y=3x
(x+3x+z)=13000
(4x+z)=13000------1
also
(4x+z)13000=503000----2
hence the systems of equation is
(4x+z)=13000------1
(4x+z)13000=503000----2
