Find all two digit numbers that when you reverse their digits then add that to the original number you get 55?
The original number, written as " T U ", has the value (10T + U). When you reverse the digits, the new number has the value (10U + T). Adding the two numbers: (10T + U) + (10U + T) = 55 11T + 11U = 11(T + U) = 55 T + U = 5 All possible two-digit numbers that satisfy (T + U = 5) are: 1423 32 41

What is the total of digits used in numbers from 51 to 5001?
To find the total number of digits used in numbers from 51 to 5001, we can break it down into two parts. Numbers from 51 to 99: Each number in this range has 2 digits, so there are 49 numbers in total, resulting in 49 x 2 = 98 digits. Numbers from 100 to 5001: Each number in this range has 3, 4, or 5 digits. a. For numbers from 100 to 999, each number has 3 digits, so there are 900 numbers in total, resulting in 900 x 3 = 2700 digits. b. For numbers from 1000 to 5001, each number has 4 or 5 digits. There are 4002 numbers in total, and if we assume each has 4 digits, it would be 4002 x 4 = 16008 digits. Adding all these together, the total number of digits used in numbers from 51 to 5001 is 98 + 2700 + 16008 = 18706 digits.
