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
Answer:
EBC and ABE, as well as ABD and ABE
Step-by-step explanation:
Supplementary angles form an 180 degree angle. In other words, they form a straight line.
EBA and DBC are each greater than 90 degrees and are vertical angles, not supplementary angles.
EBC and ABE form a straight line. So they are supplementary angles.
ABD and ABE form a straight line. So they are also supplementary angles.
CBE and ABD are each less than 90 degrees and are vertical angles, not supplementary angles.
So, EBC and ABE, as well as ABD and ABE are the correct choices.
