Answer:
x = 64
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Sum the given angles and equate to 360
x + 2x + 114 + x - 10 = 360, that is
4x + 104 = 360 ( subtract 104 from both sides )
4x = 256 ( divide both sides by 4 )
x = 64
Answer: see below
Step-by-step explanation:
The charges is always at least $80 just for the plumber to show up. The, it increases by $60/hour.
We represent cost, c in dollars, as below.
part A --> c = 80 + 60h
where h is the number of hours.
For 3 hours work, c = 80 + 60(3) = 80 + 180 = $260
part B --> $260
I hope this helps.
