Question 989359: If x≤y≤z.
And x≤y is saying x is less than y
and y≤z is saying y is less than z
then y is either between the two values.
But what if I am trying to isolate only y and understand it specifically. Isn't there something to where I could take out x and y and make it so that y≥x? so to say that y is greater than on equal to x. I forget the name of this rule.
Thanks

x%3C=y, means x is less than or equal to y.
y%3C=z, means, y is less than or equal to z.

Further, in the inequality x%3C=y%3C=z, where is y on a number line?

Your statement is not a strict inequality, and allows for x and y to be equal, or y and z to be equal, or for x, and y, and z all to be equal.

This statement,
x%3Cy%3Cz is a strict inequality, and here, y is BETWEEN x and z.

No. means that x is less than OR equal to y. If you want to ignore the part of the statement that says then go ahead, so long as nothing you do subsequent to that tries to assert that either or is larger than
