Answer:
x = 36
Step-by-step explanation:

Subtract x and 36 from both sides.

Divide both sides by -1.

Square both sides.

Subtract 144x from both sides.

Factor the right side.



Since the solution of the equation involved squaring both sides, we musty check the answer for possible extraneous solutions.
Check x = 36:





Since 0 = 0 is a true statement, the solution x = 36 is a valid solution.
Take 60 minutes and times that by 60 to find your seconds. (s)
Next, take 240 times 3 to find your feet. (f)
Then, take your feet divided by seconds. (T)
f/s =T

Answer:
Step-by-step explanation:
3x-2y= 100
3x= 10 +2y
x =(10+2y)/
In 18 hours = 92700
In 1 hour it would be: 92700/18 = 5150 riders
