Drag and drop the appropriate property next to each step to justify the step.

The given equation is

Here we have to solve for x.

First we need to get rid of 9, and for that, we add 9 to both sides. That is

     (Addition property of equality)

Now we need to get rid of 2, and for that, we divide both sides by 2.That is

  (Division property of equality) .

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
