12/3 = 4 ft
4x2=8inches
Each side of the rug on the scale drawing would be 8 inches long if 2inches is equivalent to 3 feet.
9 = 2(6) - b
9 = 12 - b
-3 = b
Solve the inequality for x:
5x - 3 ≤ 7x +7
Subtract 7x from each side:
-2x -3 ≤ 7
Add 3 to each side:
-2x ≤ 10
Divide both sides by -2, also when dividing both sides of an inequality you flip the direction of the inequality sign:
x ≥ -5
The dot will be on -5, because the inequality includes equal to, the dot is solid and is greater than, the arrow will point to the right.
The correct answer is D.
