Answer:
Step-by-step explanation:
Move the decimals to the right until .03 equals 3.0, then move the decimals of 5.5 the same amount of times, and you have 540/3=180

Answer:

Step-by-step explanation:
Multiply numerator and denominator by the "conjugate" of the denominator.

__
This is done in different scenarios in order to take advantage of the factoring of the difference of squares. Square root terms and imaginary terms in the denominator can be eliminated in this way.
a² - b² = (a -b)(a +b)
The equation of a line that passes through

and has a slope of m is

so given the point (3,1) and slope -2
(3,1), (x1,y1)
x1=3
y1=1
m=-2
the equation is
