Based on the triangle sum theorem:

What is the Triangle Sum Theorem?The triangle sum theorem states that if we add up all the three interior angles in a triangle, the sum we would get would be equal to 180 degrees.
Given the following are interior angles of a triangle:

The unit method is a method of finding the value of one unit and then finding the value of the required number of units. For simplicity, always write what you calculate on the right and what you know on the left.The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.It is given that a truck driver drove 119 miles in 3 1/4 hours .
On simplifying the time , we get
[tex]3\frac{1}{4} =\frac{3\times4+1}{4}\\\\ 3\frac{1}{4} =\frac{13}{4}[/tex]
which means that truck driver drove 119 miles in [tex]\frac{13}{4}[/tex] hours .
Using unitary method , we get
[tex]\frac{13}{4}[/tex] hours is taken by driver to complete = 119 miles

A rental car agency charges $180 per week plus $0.25 per mile to rent a car. How many miles can you travel in one week for $382.50?

Step-by-step explanation:
382.50-180= 202.5
202.5 / 0.25= 810
Hope this helps!
Answer:
810 miles
Step-by-step explanation:
$180 a week is the fixed cost so we subtract this first.
($382.50 - $180 = $202.50)
The number left is the amount of dollars charged per mile.
So if we divide this number by $0.25, we get how many miles travelled.
($202.50 ÷ $0.25 = 810 miles)

The inverse function of f(x) = (x + 2)/(x - 3) is given as follows:
[tex]f^{-1}(x) = \frac{3x + 2}{x - 1}[/tex]
How to obtain the inverse function?The function in this problem is defined as follows:
f(x) = (x + 2)/(x - 3).
Using the notation y = f(x), it is given as follows:
y = (x + 2)/(x - 3).
To obtain the inverse, the first step is exchanging the variables x and y, as follows:
x = (y + 2)/(y - 3).
Now the variable y must be isolated to obtain the inverse function, as follows:
xy - 3x = y + 2
xy - y = 3x + 2
y(x - 1) = 3x + 2
y = (3x + 2)/(x - 1).
Hence the inverse function is given by:
[tex]f^{-1}(x) = \frac{3x + 2}{x - 1}[/tex]
