Hard looking algebra problem

If x and y are positive integers, is (2+x) / (3+y) greater than (2+y)/(3+x)?


1) x+y = 3
2) x > y

I am not sure where you get 69 from but draw a chart on this one to help you. Let January Employees = x then, December: (1.15)x Given, employees in december = 460 So, 1.15x = 460. Solve for x, x = (460)/(1.15) = 400. Company P has 15% more employees in December than it had in January, If company P h...

So, essentially: We know the p and q are prime numbers. Are they even or odd numbers? They can not be even because there are no two digit even numbers. They have to be odd. So our possibilities of digits are : 1, 3, 5, 7, 9 However, the digits can NOT be 5 because that would result in one of the num...
