Rational numbers are the numbers that can be written as the fraction of two integers and absolute value is the distance a number is away from 0. If we look at a number line, the absolute value is the distance any number on the number line is away from 0. Distance is always positive, so our absolute value is always 0.
219+159≤x≤369+309
The answer can then be simplified to
378≤x≤678
I = prt
To solve for r divide both sides by p and t.
r = I /pt
