<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that:-
A roof repairman charges a $60 consult fee, and then $45 per hour to complete repairs. if the homeowner pays a total of $195.
The time will be calculated as:-
Total amount = $195
Now the fixed consulting cost will be $60 and will be deducted from the
total amount.
Variable cost = 195 - 60 = 135
The $45 per hour charge so for $145 the time will be:-
Time = 135 / 45
Time = 3 Hours
Therefore the time spent by the repairman there will be 3 hours so the correct answer is option D.

The absolute value of a quantity is 5 if that quantity is either 5 or -5.
So, the two solutions are
Now, there is a bit of ambiguity here: we are not told who 
and 
are exactly, and yet the value of 
depends on our choice.
If we choose a = 2 and b = -3, then the value of a-b is 5
If we choose a = -3 and b = 2, then the value of a-b is -5
