Find the difference in speed:

2.2 - 1.4 = 0.8 m/s

Now divide the difference in speed by time:

0.8 m/s / 4 seconds = 0.2 m/s/s

After the music store he had $14 left, because 21:3=7 and 7x2 equals 14.

After the drink, he has $3.5 left, because 14:4=3.5 and 3.5x1=3.5.

Conclusion: that is one expensive drink. (Answer is 3 dollars and 50 cents. Hope this helped:)

Find the value of x.
Novay_Z [31]

Answer:

x = 50°

Step-by-step explanation:

Angles in a quadrilateral add to 360°

First work out the interior missing angle

360° - ( 40° + 80° + 110° ) = 130°

Angles on a straight line add to 180° so

180° - 130° = 50°
