Answer:
   "associative"
Step-by-step explanation:
The associative property lets you change the grouping of terms of a sum or of a product.
___
For example, you can rewrite 
   (5 + 4·3) -2
as
   5 + (4·3 -2)
but the associative property does NOT allow you to change the grouping to ...
   (5 +4)·3 -2 . . . . . not a valid rewrite

Answer:
We need to find the value of b to make 8b - 27 be equal to 5, so:
8b - 27 = 5
We solve the equation:
8b = 5 + 27
8b = 32
We divide both sides by 8:
b = 32/8 = 4
So now, we know that b=4, and we can verify:
8*4 - 27 = 5
32 - 27 = 5 TRUE
