Step-by-step explanation:
3x-12 ≥7x+4
Subtract 3x from both sides
-12 ≥4x+4
Subtract 4 from both sides
-16 ≥4x
Divide each side by 4
-4 ≥x
From point 4, you use a closed circle and the arrow is facing towards 0
Volume is measured in cubic units.
So the ratio would become 6^3: 5^3 = 216:125
The answer would be A.
