1g I think am not sure u didn't give a lot of information on this problem
-20x is probably the correct answer
Hey there! Hello!
So, for this problem, I don't really see an answer choice that fits along with this description?? The last one is the closest to the answer I believe it is, but still doesn't fit exactly:
Twice a number = 2n
Three more than = +3
Final equation = 2n+3
Perhaps you have a typo either in your question or your answer problem, or I'm just way too tired. Either way, I hope this helped you out, and feel free to ask me any additional questions you may have.

Answer:
A. t=4n+950
B. h=9.5n
C. d=9.5n-(4n+950)
D. The tortoise will finish first.
Step-by-step explanation:
To find the first two equations, we put the rate at which they are traveling in front of the n, and then add where they start. Since the tortoise gets a 950 meter head start, we add 950. The hare is starting at the start line so we don't need to add anything.
For answer c, we need to subtract the two equations from each other to figure out when they would pass each other. d=(equation h)-(equation t).
For the final answer, all you need to do is plug the first two equations into a graph, and then find where each line is at the point of y 1,600. (To make the graphs I replaced the n with x and the t and h with y.) Using this, we are able to see who got there first, which was the tortoise.
