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, they are equivalent.
Step-by-step explanation:
They are equivalent, to see this, simplify the expression.
Distribute into the parenthesis.
5(y)- 5(2)
Then simplify into...
5y-10
This is equivalent to 5y-10
<h2>5y-10 =
5(y-2)</h2>
Answer:
x=2
Step-by-step explanation:
Since the angles are equal, the side lengths are equal (isosceles triangle)
12 =6x
Divide by 6
12/6 = 6x/6
2= x

The number

isn't equal to zero because the division by zero is not defined. So we can represent rational numbers by a repeating or terminating decimal, for instance in the following four exercises we have:
