how many integer values are there for x such that 1 < 3 x + 5 < 17 ?
the inequality given is 1 < 3 x + 5 < 17 it can further reduced to - 4 < 3 x < 12 finally - 4 / 3 < x < 4 so can only take 5 integer values i . e . - 1 , 0,1 , 2,3 correct answer - d
floor(subtract(divide(subtract(17, 5), 3), divide(subtract(1, 5), 3)))
