Variable x is ryans miles
amy-ryan=answer
40-31=x
x=9
ryan ran 9 miles
hope this helps
40-31=x is the equation
1) 2m/s = 2*18/5 =7.2Km/h
2)In 3 hour, he would travel, 7.2*3 = 21.6Km.
You haven't shared "the given value of x," or, if you have, you haven't drawn attention to it.
Just suppose we were to choose x = 4 as a possible solution and then try to find a value of the parameter k that would make x = 4 an actual solution.
2(4) + 4k - 9 = (4)(4) - (4) + 1
Then 8 + 4k - 9 = 16 - 4 + 1, or 4k - 1 = 13. Then 4k = 14, and k = 14/4, or (after reduction) k = 7/2
If the parameter k equals 7/2, then x = 4 is a solution to the given equation.
To check this out further, start with the proposed solution x = 5 and find k.

Step-by-step explanation:
The quantity of water in the tank after 9 days is 19 liters.
<h3>How much water is in the tank after 9 days?</h3>
The exponential equation that can be used to determine the quantity of water in the tank after 9 days is : 9728 x (0.5)^t
Where t is equivalent to the number of days
9728 x (0.5)^9 = 19 liters
