Answer:
It removes the repeating part of the decimal from the equation.
Step-by-step explanation:
Described here is the process of converting the repeating decimal fraction into fraction in the form of p/q
1) --------------
2) --------------
3) --------------
- 10 x - x = 5.555555 - 0.555555
 - 9x = 5
 - x = 5/9
 
So the purpose of step 3 here is to remove the repeating part of the decimal from the equation
Correct option is the first one.

Answer:
C) The variable x represents the independent variable.
Step-by-step explanation:
The given function is 
.
g(x) is NOT the multiplication of g and x because g is a function of x.
 is the input of the function.
 is the output of the function.
The variable 
 is called the independent variable because we plug in values of x to find g.
The variable g represents the output of the function NOT the input.
The correct choice is C
