Erik and Nita are playing a game with numbers. In the game, they each think of a random number from zero to 20. If the difference between their two numbers is less than 10, then Erik wins. If the difference between their two numbers is greater than 10, then Nita wins.
What is the range of numbers that will win the game for your player?
Given: Choose a number between 0 and 20. If the difference is less than 10 then Eric wins. Let us x is Eric's number. 0 < x < 20 If Eric wins. |x -7| < 10 |x-7| < 10 → -10 < x-7 < 10 → -10 + 7 < x - 7 + 7 < 10 + 7 → -3 < x < 17
Taking into account that the number must be given between 0 and 20. 0 < x < 20 -3 < x < 17
