A33 gram sample of a substance that's
used for drug research has a k-value of
0.1124.
n= noekt
no = initial mass (at time t = 0)
n = mass at time t
k = a positive constant that depends on
the substance itself and on the units
used to measure time
t = time, in days

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
