Answer:
8 shifts.
Step-by-step explanation:
Brianna worked a total of 44 hours stacking shelves.
If she worked 
hour shifts,
How many shifts did she work?
So 1 shift takes 5.5 hours
The number of shifts she worked in 5.5 hours is;
= 8 shifts.
The answer:
the main rules of the use of logarithm are
loga[a] = 1
loga[AxB] =loga[A] +loga[B] for all value positive of A and B
loga[A/B] = loga[A] - loga[B] for all value positive of A and B
in our case, <span>log8 4a (b-4/c4)
so it is equivalent to </span>log8 4a + <span>log8(b-4/c4)
and since </span>loga[A/B] = loga[A] l - oga[B] , log8(b-4/c4) =log8(b-4) - log8(c4)
the possible expression:
log8 4a (b-4/c4) = log8 4a + log8(b-4) - log8(c4)
Answer:
-2r = 2 - Subtract 11 from both sides
r = -1
