If a "certain number of men" less 10 takes 20 days (twice as long) to finish the piece of work, then the "certain number of men" who can finish the work in 10 days would 20. If it takes 10 men less twice as long to do the work, then twice 10 men (20) can finish the job in 10 days.

(92 x 2) - (9 x 2) = 162 - 18 = 144 The number is therefore 9.
Twenty more than twice a number is 52
2x + 4 < x x < -4

Example:VERBAL SENTENCE:Seven more than twice a number is four less than thrice the number.MATHEMATICAL EQUATION:(seven more than) (four less than)(twice a number) is (thrice a number)2x + 7 = 3x - 4=Earljoyce8♥=Hope this helps!!
X = number. 4X + 9 = 2X - 15 ===========
14 more then a number cubed minus twice the number
2x-3=x+2 answer x=5
It seems that each number is alternately one less and one more than twice the previous number.
