Since the "leading" runner in a race would be found in the first position, because he or she is in the lead, it means they are first, then I suppose I would find the "leading coefficient" in the first place in a polynomial as well.
20/15=N/27
Do cross multiplication.
20x27=540
540/15=39
So the answer ia 39.
D for sure I hope it helps and I know I’m 100% right because I already had this question somewhere else dude so yeah
5.5 hours. 5 hours and 30 minutes
The total pages she wants to finish (360) minus the pages she has read (112.5) equals to 247.5
Then divide it by the 45 (the rate of pages she reads per hour)
5.5 hours.
You can subtract 4 from 13 then subtract 4 again
