Answer:
D. The given expression is sixty - eight less than (1271 ÷ 1/5)
Step-by-step explanation:

Expression should be:
Sixty - eight less than (1271 ÷ 1/5)
$18.40 with the tip added to the price because the tip will be $2.40
All angles in a quadrilateral add to 360
x is supplementary to that other angle, call it y
the angles inside are 40, 80, 110 and y
40+80+110+y=360
230+y=360
minus 230 both sides
y=130
that is supplementary to x (adds to 180)
x+y=180
x+130=180
minus 130 both sides
x=50
x=50 degrees
Ok this is how it work:
1+4=5
2+5=12=2+1+4+5=12
3+6=21=12+3+6=21
8+11=? do the same to that take 21+8+11=40
ask me if you don't get it. I explain it further.
