I'd appreciate it if you'd ! : ) sandy is driving cross country. she has covered 200 miles from the east coast towards the west coast. she has driven this distance in 2 days. if sandy continues to drive at this rate, which equation represents the total number of miles , m, she would cover in d more days? m=300d m=200d+100 m=2d m=100d+200

Ответ:
The answer to your question would be
m=100d+200
why?
Well it took her 2 days to drive 200 mile so she drives 100 miles per day.
since she is already gone 200 miles you just add 100 times the days it takes.
Hope this helps

Let's assume number of SFG = x
and number of LFG = y
Given that 2 points for a short field goal, and 3 points for a long field goal.
Total Score = 2x+3y
Also, Total score = 36 (given in the question)
So we have the equation
where x and y are integers.
when SFG=0, then x=0 and so 3y=36.
y=12 i.e. LFG = 12
So the extreme case is (0,12) i.e. SFG=0 and LFG=12.
Other cases would be integral vales of (x,y) which satisfy the equation 2x+3y=36.
So (3,10) , (6,8) , (9,6) , (12,4) , (15,2) , and (18,0) are other cases.
Hence final answers are (x,y) = (0,12) , (3,10) , (6,8) , (9,6) , (12,4) , (15,2) , and (18,0)
