Answer:
The number of bleachers seat sold = 200
The number of end zone seats sold =200
The number of excellent seats sold =100
Step-by-step explanation:
Let there are bleachers seats =x
The number of zone seats =y
The number of excellent seats =z
So, we can set up equations for given sentences as
x+y+z= 500
20 x+30 y+40 z=14000
x=y
Substitute x as y into first two equations
y+y+z=500
20 y+30 y+40 z=14000
Simplify each
2 y+z=500
50 y+40 z= 14000
Multiply 2 y +z=500 by -40 to eliminate z terms when we add them.
-80 y-40 z=-20000
Add this with 50 y +40 z=14000, which gives
-30 y=-6000
Divide both sides by -30
y=200
Now, plug in y as 200 into any of the equations to find z.
2(200)+z=500
400+z =500
Subtract both sides 400.
z=100
Now, we know x=y
So, x=200

Answer:
D: 65 km²
Step-by-step explanation:
The formula for area of a hexagon when given the base is
A = (3/2)(√3)b² where b is the length of the base
Here, b is given as 5, plug that in and simplify
A = (3/2)(√3)(5²)
A = (3/2)(√3)(25)
A = (75√3)/2
A ≈ 64.95 ≈ 65
