Answer:
H. the number of orchestra seat is 900
Step-by-step explanation:
Step one:
let the number of orchestra seat be x
and balcony seat be y
cost of orchestra= $50 each
cost of balcony =$40 each
total tickets= 1500
x+y= 1500----------1
amount earned= $69000
50x+40y=69000--------2
The system of equation for the situation is
x+y= 1500----------1
50x+40y=69000--------2
from 1, x=1500-y
put this in equation 2
50(1500-y)+40y=69000
75000-50y+40y=69000
-10y=69000-75000
-10y=-6000
divide both sides by -10
y=-6000/-10
y=600
put y= 600 in equation 1
x+600= 1500
x=1500-600
x=900
Answer: yes the two sides of an equation always equal each other regardless of which side of the equal sign they are on.
Step-by-step explanation:
Answer:
Step-by-step explanation:
x is the side opposite the angle of 12 degrees
we know the hypotenus is 20 ft
we don't know what the side length that is adjacent to the angle
----------------
ADJ/HYP = cos (of the angle)
OPP/HYP = sin (of the angle)
sin/cos = tan (of the angle) = ( OPP/HYP) / (ADJ/HYP) = OPP/ ADJ
How would we solve for x the side opposite the angle?
So who is right?
6 divided by the number the teacher gave u lol
