what’s the average of 279 minutes?

1 hour = 60 minutes

The time values given, in minutes, are:

25, 55, 60, 94, and 46

going from monday to friday in that exact order

Add up the values, then divide by 5. This is because there are 5 values

So adding up the values gets us: 25+55+60+94+46 = 280

Then dividing by 5 leads to this 280/5 = 56

note: you must convert the "1 hour" to "60 minutes" because each time value must be in the same units. Otherwise, its like mixing apples and oranges which makes no sense.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
