Answer:

170

Step-by-step explanation:

19 45 - 16 55

For convenience, let's find the lapse from 17 00 till 19 45, it's simple 2 hours and 45 mins.

Now add the 5 mins we neglected (from 16 55 to 17 00).

That's 2 hours and 50 mins

1 hour = 60 mins

2 hours = 120 mins

2 hour 50 mins = 170 minutes

2(1/4x + 4) = 3(x -2) PLZ HELP
frozen [14]
Distribute 2 and remove parentheses :
1/2x+8=3x-6
Multiply both sides of equation by 2:
x+16=6x-12
Move terms:
x+16-6x=-12
x-6x=-12-16
Collect like terms:
-5x=-28
Divide both sides:
x=28/5
