<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.

Answer:
Step-by-step explanation:
make two equations
one equation is about the money and one is about counting how many coins
Money equation : .10d + .25q = 5.80
this assigns the value of the dimes at 10 cents and the value of the quarters at 25 cents.
counting equation: d + q = 40
so the answer is C
You would use L to measure the amount
