Answer:
The correct choice is <u><em>option A. 2 < x < 10/3</em></u>
Step-by-step explanation:
|3x - 8| < 2
= -2 < |3x - 8| < 2
3x - 8 > -2 and 3x - 8 < 2
+8 +8 +8 +8
----------------- ------------------
3x > 6 3x < 10
/3 /3 /3 /3
----------------- -------------------
x > 2 x < 10/3
= 2 < x < 10/3
It took 6 hours for the temp. to drop to 7.8
A fair die has 6 sides so a 1/6 chance for each number
So divide 480/6= 80
80 times for each number, 80 for 6
I just learned a short time ago how to convert a repeating decimal to a fraction.
-- Take the repeating part of the decimal. In this one, it's '764' .
-- Make a fraction out of it by writing it over the same number of 9s.
The fraction here is 764/999 .
-- Simplify it if possible and if you feel like it.
764/999 can't be simplified. (I think.)
So the rational expressions for this decimal are
(5 and 764/999) or 5759/999 .
All you have to do is find the important info and use it and do whatever and all you have to do is take the numbers do the question and ur done :D
