4/7 = 12/21
12/21 = x + 3/21
9/21 = x
Hope this helped!!
Answer:
r(n) = 1000·(2/5)^n
Step-by-step explanation:
Since the tortoise travels 3/5 the remaining distance, the remaining distance at the end of the day is 2/5 of what it was at the beginning of the day. So, the function can be modeled by an exponential with a "growth" factor of 2/5:
r(n) = 1000·(2/5)^n
where r(n) is the number of remaining feet after n days of travel.
(n+12) • 9
to simplify, use the distributive property
9 • 12 = 108
9 • n = 9n
9n • 108
