Step-by-step explanation:
Lakelyn can swim at a rate of 250 yards every 5 minutes. She can run 6 miles an hour and bike 12 miles an hour.
Therefore, her running speed is 6 miles per hour.
Therefore, the function that models the running distance (d) in miles and the time span of running (t) in hours is given by
d = 6t ............. (1)
Using the above equation we can calculate the time required by her to run 18 miles.
So, 18 = 6t
⇒ t = 3 hours. (Answer)

Answer:
12
Step-by-step explanation:
Move all terms containing x to the left, all other terms to the right.
Add '9' to each side of the equation.
-9 + 9 + 7x = 75 + 9
Combine like terms: -9 + 9 = 0
0 + 7x = 75 + 9
7x = 75 + 9
Combine like terms: 75 + 9 = 84
7x = 84
Divide each side by '7'.
x = 12
Simplifying
x = 12
