Answer:
13.5 hours
Step-by-step explanation:
9hrs= 2 painting
9 divided by 2= 4.5
9+4.5= 13.5
-6/3 division sign 2/-9
To solve: multiply by reciprocal inverse
-6/3 x -9/2= 54/6 or 9
The answer is 3.
Since you do the parentheses first, you will figure out what why is. Y = 3, because 3*3 =9, and 9-9=0.
