in the box, how much space has NOT been used?

Answer:
28.75 cm^3 of space not used

Answer:
y = 24
Step-by-step explanation:
3x + y = 6
Solve for y
Subtract 3x from each side
3x -3x+ y = 6-3x
y = 6-3x
Let x = -6
y = 6 -3(-6)
=6+18
=24
Rationalize.
This can be further simplified to the decimal:
-0.43006...
I hope this helps :)
Subtract 8 from both sides to get y = 8 as your final answer.
