Answer: x = 111
Step-by-step explanation:
This question makes use of Remote Exterior Angles.
<u>Remote Exterior Angles</u><u> states that the value of a remote exterior angle(x here) is always equal to the sum of the two remote interior angles(82 and 29 here)</u>.
Thus, x = 82 + 29.
Thus x = 111

14+7= 21
8 x 21=168
8 x 7= 56
224
First I would distribute the left part like so:
12x - 18 - (5x + 7)
Then I would distribute the right side like so: (I'm just distributing a negative sign)
12x - 18 - 5x - 7
Then I combine like terms like so: (12x and -5x)
7x - 18 - 7
Then I would combine the other like terms like so: (-18 and -7)
7x - 25
I hope that helps! Feel free to let me know if you have any questions! :3

Distance covered = 2 km
time taken = 30 minutes = 0.5 hour
speed = distance/time = 2/0.5 = 4 km/h
