If your player is Erik, write an inequality that shows all of the ways that Erik will win
stellarik [79]

An inequality that shows all of the ways that Nita will win if Erik chooses 17 is

  • Eric will win if Nita chooses 7 and he chooses and number that is less than 17 (ex. n<17).
  • Nita will win if Eric chooses 17 and she chooses a number less than 8 (ex. n<8).

<h3>What is an Inequality?</h3>

This refers to the relation in mathematics that makes an unequal comparison between two numbers or expressions.

Therefore, according to the rules of the game, they would have to make random selections from 0 to 20 and if the difference between their two numbers is less than 10, then Erik wins, the inequality that would show all of the ways that Nita will win if Erik chooses 17 are listed above.

Hence, we can see that the complete question goes thus:

"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.

Use what you know about inequalities and absolute values to better understand the game."

The tens digit is 9 more than the ones digit
zavuch27 [327]
This number should be 10.

The tens digit the the 1st number on a two-digit number. Because the highest number you can go without creating a hundredths place is a 9, and the question says the ones-place (the last digit), this has to make this number 0. If it were to be 1 or anything higher, it would have to create a hundredths place if the rule of the question were to be followed.

Example: 
If ones-place were 1, then following rule: 1+9 = 10
Your number would end up being 101 instead of a tenths place number.

I hope that made some sense somewhere!
