Final answer:
To find the numbers, let's set up and solve an equation representing the given information. The numbers are 39 and 50.
Step-by-step explanation:
To solve this problem, let's denote one number as x and the other number as x + 11. We can set up the equation: x + (x + 11) + 17 = 90. Simplifying this equation, we get 2x + 28 = 90. Subtracting 28 from both sides gives us 2x = 62. Finally, dividing by 2, we find that x = 31. Therefore, the numbers are 31 and 31 + 11, which is 42. Therefore, the correct answer is D) 39 and 50.
