MP = 15 -3 = 12
h/MP = 3/h
h / 12 = 3/h
h^2 = 36
h = 6

Answer: the fixed cost to rent the limousine is $200
Step-by-step explanation:
Let x represent the fixed cost rent the limousine.
Let y represent the cost of of hiring the driver of the limousine per hour.
It cost $500 to rent a limousine for 5 hours. This means that
x + 5y = 500 - - - - - - - - - - -1
It costs 800 to rent a limousine for 10 hours. This means that
x + 10y = 800 - - - - - - - - - - -2
Subtracting equation 2 from equation 1, it becomes
- 5y = - 300
y = - 300 /- 5
y = 60
Substituting y = 60 into equation 1, it becomes
x + 5 × 60 = 500
x + 300 = 500
x = 500 - 300
x = 200

Answer:
5
Step-by-step explanation:
This is a special right triangle: 5, 12, 13
Or you can solve using the Pythagorean Theorem (a^2+b^2=c^)
--> 13^2-12^2=b^2
-->169-144=b^2
-->25=b^2
b=5
