57. ON Monday Jordan biked 2 ¾ miles
=> On Wednesday he biked twice as many miles as he did on Monday
=> 2 (2 3/4)
On Friday he biked 8 ¼ miles.
Now, let’s find out the difference of miles did Jordan biked on Wednesday and Friday.
=> 2 ¾ convert to decimals = 2.75
=> twice as 2.75 = 2(2.75)
=> he biked 5.5 miles or 5 and ½ miles on Wednesday
=> 8 and ¼ or 8.25 – 5.5 = 2.75
Thus, he biked more than 2.75 miles on Friday compare to Wednesday.
Answer: C. 625 and 81
Step-by-step explanation: A relatively prime pair is a pair in which in both numbers given, the only number that can go into each number is one. In 112 and 36, we know 2 can evenly go into each number because they both end in a positive number (112/2 is 56 and 36/2 is 18.) This means A is incorrect. As for B, 11 can evenly go into each number, leaving you with 25 and 7. B is incorrect. And then there's D. 5 can go into each number giving you 160 and 19. D is incorrect.
C is correct because the only numbers that can go evenly into 81 is 1, 3, 9, 27, and 81. None of these numbers, except one can go into 625 also.
