<h3>Answer: Choice D</h3>

Explanation:

To solve for x, aka isolate it, you add 11 to both sides. Then you divide both sides by 2 like so:

2x-11 \ge 5\\\\2x \ge 5+11\\\\2x \ge 16\\\\x \ge \frac{16}{2}\\\\x \ge 8\\\\

The inequality sign stays the same the entire time. It only flips if you divide both sides by a negative number, but that doesn't happen in this case.

The perimeter of a parallelogram EFGH is 48 in. If EF is 5 in les than EH, find the lengths of all four sides
DiKsa [7]
Let the lengths of EH and FG = x
Let the lengths of EF and HG = x-5
Solve,
X + X + (X-5) + (X-5) = 48
4X - 10 = 48
4X = 58
X = 14.5
EH= 14.5
FG = 14.5
EF = 9.5
HG = 9.5
