This is a simply problem. Just divide both sides the coefficient of x. Which is -2.
And the answer will be x = -4

Answer:
The answer to your question is:
x = 43°, y = 137° and z= 43°
Step-by-step explanation:
-If lines L and M are parallel, that means that 43° and z are corresponding angles and they measure the same.
z = 43°
- y and 43° are supplementary angles , so
y + 43 = 180
y = 180 - 43
y = 137°
- x and z are vertical angles, so they measure the same
x = z = 43°
Answer:
Jennifer's speed is 2.4 miles/hour
Kamlee's speed is 2 miles/hour
Step-by-step explanation:
To find their speed,
Speed can be determined from the formula below,

Also, to determine the speed in miles per hour (miles/hour), we will convert the time spent by each of them to hour (NOTE: 60 minutes = 1 hour)
For Jennifer,
Distance = 4/5 miles
Time = 20 mins (Convert to hour)
∴Time = (20/60) hour = 1/3 hour
Hence,




Hence, Jennifer's speed is 2.4 miles/hour
For Kamlee,
Distance = 5/6 miles
Time = 25 minutes (Convert to hour)
Time = (25/60) hour = 5/12 hour
Hence,




Hence, Kamlee's speed is 2 miles/hour
