If the digits are a, b and c, the number n is 100a+10b+c
Here are the equations:
a number equals fifteen times the sum of its digits:
100a+10b+c = 15(a+b+c)
if its digits are reversed, the resulting number exceeds n by 396:
100a+10b+c+396 = 100c+10b+a
the one’s digit is one larger than the sum of the other two:
a+b+1 = c
Solving it gives you a=1, b=3, c=5, the number is 135.
Circumfernce=diameter times pi
given that we should use 3.14 for pi
and diameter is 11.9
circumfernce=11.9 times 3.14=37.366
the circumference is 37.366cm
Answer: Here are two inequalities. Hope this is good.
4<x<9
9>x<4
Answer:1/5 = 2/10 = 3/15 = 4/20 = 5/25 = 6/30 = 7/35 = 8/40 = 9/45 = 10/50 = 11/55 = 12/60 = 13/65 = 14/70 = 15/75 = 16/80 = 17/85 = 18/90 = 19/95 = 20/100 = 21/105 = 22/110 = 23/115 = 24/120 = 25/125 = 26/130 = 27/135 = 28/140 = 29/145 = 30/150 = 31/155 = 32/160 = 33/165 = 34/170 = 35/175 = 36/180 = 37/185 = 38/190 = 39/195 = 40/200
