9. A plumber charges $25 to come to your house. He also charges $60 for each hour that he works. The plumber charges a total of $145. Write an equation that could be used to find the number of hours the
plumber works and solve it

The formula would be (where "h" is the number of hours and C is the total amount of money given to the plumber). And if we use this formula we will know that In this case, the plumber was working for 2 hours

Step-by-step explanation:

From the question itself, we know if we let "h" represent the numbers of hours the plumber works and "C" represents the total amount of money paid to the plumber, then we can write the following equation...

C = 60h + 25

From here we can rearange the formula and get the following...

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
