Answer:
the answer should be 76.333...(nearest tenth 76 ) or 26.
Step-by-step explanation:
since she was already at 151 feet below, I subtracted 229 with 151 and got the answer 78 so after it I just divided it with 3 cause she went down in 3 seconds and the answer could be 76.333 if we dont subtract 229 with 151.
(sorry, my explanation is bad)
The answer is D!!!!!!!!!!!!!
N-3n=14-4n
N-3n+4n=14
2n=14
N=14÷2
N = 7 To check substitute 7-3(7)=14-4(7)
7-21=14-28
-14=-14
