answers:

1. c
2. a
3. d

i only know #2 because i got it wrong the first time ^^;

NEVER MIND THANK YOU SO MUCH DAMON SUCH A BIG HELP 100% god bless you <3 ;)

does that make 21 or 18?

Keith is right

the same as q - 9 = 12

add 9 to both sides

To find the solution to the equation q + (-9) = 12, we need to isolate the variable q. Here's how:

Step 1: Remove the parentheses:
q - 9 = 12.

Step 2: Move the constant term (-9) to the other side of the equation by adding 9 to both sides:
q - 9 + 9 = 12 + 9.
This simplifies to:
q = 21.

Therefore, the solution to the equation q + (-9) = 12 is q = 21.
