Answer:
135 degrees
Step-by-step explanation:
(8x-7)+(12x+57)=180
combine like terms
20x+50 = 180
subtract 50 on both sides
20x = 130
divide by 20
x = 130/20
x = 13/2
x = 6.5
cpq = 12x+57
cpq = 78 + 57
cpq = 135

Answer:

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or 
Let
x-----> the speed of the elevator
y----> the weight it carries
so

<em>Find the constant k</em>
For x=10 ft/sec, y=400 lb
substitute

The equation is

Find the speed for y=500 lb
substitute in the equation
