Steps to solve:
2(n + 3) = 2n + 3
~Distribute left side
2n + 6 = 2n + 3
~Subtract 6 to both sides
2n = 2n - 3
~Subtract 2n to both sides
n = -3
Best of Luck!
The unknown digit is 7 because 6.471 is greater than 6.470 and less than 6.48.
8+11 is 19

Answer:
D
Step-by-step explanation:
If we isolate the variable in each given compound inequality, we can quickly realize that D is correct.

x is less than or equal to four (solid point on 4 with line going left), but greater than -1 (open point going right).
Signs with 'or equal to' have solid points, and signs without are not solid.
I hope this helps!
