.40 x = 64
x = 64/.4 = 160 students al together
at x = 3 both pieces must have the same value to be continuous
x+2 = 2x + a when x = 3
3+2 = 2(3) + a
5 = 6 + a
a = -1
Sorry......you can re-post it though....

distance traveled by tip of hour hand = 1 * 10π cm = 10π cm
distance traveled by tip of minute hand = 12 * 20π cm = 240π cm
250 pi cm =~ 7.854 meters
8 P 8 = 40320 ways 8! = 40320
Well ...your answer has hour hand making 2 revs and minute hand making 24 revs....thought you might edit your answer.....
eight have son only ......
Hey MHB.... hour hand makes ONE revolution in 12 hours minute hand makes 12 revs
52 c 5 = 2598960
multiplied by :
26/52 * 25/51 * 24/50 * 23/49 * 22/48 = 65780 ways ...as MHB posted .... maybe we are correct.....maybe !
f(-7) = 3 from the definition
f(0) = 2(0) -3 = -3
f(7) = 72 + 1 sum = 50
That is what I posted it goes 1 - 7 then backwards to 1 then forwards to 7 then the 2021st bag winds up in box 5 ( by my calcs)
