Answer :
Hello!
Don't let the mumbojumbo of the word problem throw you off. We have here the inequality 5t+4>19
so solving for unknown variable t which is number laps we get,
5t+4-4>19-4 subtracting 4 from both sides we are left with
5t>15 so now we divided both sides by 5 to get t alone and we have
t>15/5= t>3 laps so C is the answer. He must ride 3 laps to ride at least 19 miles
Hope this helps! Any questions please feel free to ask! Thank you much!

I am doing the procedure to get the inequality because it is important to realize that the symbol to use is ≥, given that the problem states that the number of miles is at least 19, so 19 is a valid number of miles.
Answer: option 3 or more times
Explanation:
1) First, I would like to explain how to get the inequality:
Cedric plans to ride his bicycle 2 miles to a park and then ride several times around a loop in the park that is 5 miles long.
number of times around the loop of 5 miles long: t
number of miles around the loop: 5t
number of miles from home to the park and from park to home: 2 + 2 = 4.
total number of miles: 5t + 4
He wants to ride a total of at least 19 miles => 5t+4 ≥ 19
So the inequality that models this situation is 5t + 4 ≥ 19 (notice that the inequality simbol is ≥ and not >)
2) Now we can solve the inequality, with a better understanding of what it means.
5t ≥ 19 - 4
5t ≥ 15
t ≥ 15 / 5
t ≥ 3
Then, the right answer is the option 3 or more times
