Let's say we have the fraction 
For instance, in the case of the fraction: " 1/2" ; the denominator is ' " 2 " . If the denominator is 2, we must divide 2 by our numerator which is 1 so we will create a divison problem and it will be 1 ÷ 2 = 0.5
↑ This method will always work ↑
here we plug in values of x in f(x) and g(x)
the table in attachment shows the answer
Answer:
The volume of the gas is 
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
v------> the volume of a gas in cubic centimeters
p-----> the pressure of the gas in liters per square centimeters
so

we have

substitute and solve for k

The equation is 
<em>Find the volume of the gas when the pressure is 2.2 L/cm2</em>
so
For
Find the value of v
substitute in the equation


106=x+x+5+x+8
106=3x+13
3x=93
x=31
(the sides are 31, 36, 39 respectively)
