Answer 1

The expression that is equivalent to 6n - 27 is 3(2n - 9).

Answer 2

what is the blank + 308 - 126 = 450

Answer 3

The blank is 268.

To solve the equation, you can add 126 to both sides of the equation (to isolate the variable):

+308 - 126 +126 = 450 +126
+308 = 576

Then, you can subtract 308 from both sides of the equation to find the value of the blank:

+308 - 308 = 576 - 308
0 = 268

Therefore, the blank is 268.
