It goes into 1,440 exactly 90 times.
To figure this problem out on your own, next time, just type into your calculator or work out on your paper 1,440 divided by 16 and then you'll get your answer :)
The coefficient (letter chosen) that is used does not matter as it is only to show that it is an unknown variable, if you have more than one variable you need more than one type of coefficient (use different letters for different ones you dont know).
It won 5 and there were 7 races so 7-5 = 2 which means he lost 2 races so the win-lose ratio is 5:2 or 5/2
Answer:
Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x2−1 f - 1 ( x ) = x 2 - 1 is the inverse of f(x)=2x+2 f ( x ) = 2 x + 2 .
