Answer:
1 7/33
Step-by-step explanation:
6/11 + 2/3 --> We need a common denominator
--> 11 x 3 = 33
33 is our common denominator
6 x 3 = 18
2 x 11 = 22
18/33 + 22/33 = 40/33
Convert to a mixed number
=> 1 7/33
Thus, we have our answer.

Answer:
4 hours
Step-by-step explanation:
For three visits, the electrician earned $40 × 3 = $120 in "per-visit" charges. For working x hours, he earned 20x in "per-hour" charges. The total of these came to 50x:
120 +20x = 50x
120 = 30x . . . . . . . . subtract 20x
4 = x . . . . . . . . . . . . . divide by 30
The electrician worked 4 hours that day.
