Answer:
6.66 hours, that is, 6 hours and 40 minutes.
Step-by-step explanation:
If Mike can plow a field in 12 hours, we plows 1/12 of the field each hour.
If Phil can plow a field in 15 hours, we plows 1/15 of the field each hour.
So if they are working together, they can plow (1/12) + (1/15) of the field each hour, that is:
(1/12) + (1/15) = (5 + 4) / 60 = 9 / 60 = 3 / 20 = 1 / 6.66
So if they work together, they can plow the field in 6.66 hours, that is, 6 hours and 40 minutes.

Answer:I believe it's true but I'm not sure
Step-by-step explanation:
78 minutes or
1 hour 18 minutes
Step-by-step explanation:
58 +38 = 96 degree
so we do 180 - 96 = 84 degree valur of x for one triangle
so opposite side angke x will be 96
so again we do 96 +15 = 111 degree
180 - 111 = 69 degree
