Detailed Solution & Explanation

Let's solve the inequality step by step:
52x3<x65\frac{5 - 2x}{3} < \frac{x}{6} - 5

Multiply all terms by the LCM of 3\displaystyle 3 and 6\displaystyle 6, which is 6\displaystyle 6:
6×(52x3)<6×(x6)6×56 \times \left(\frac{5 - 2x}{3}\right) < 6 \times \left(\frac{x}{6}\right) - 6 \times 5
2(52x)<x30    104x<x302(5 - 2x) < x - 30 \implies 10 - 4x < x - 30
Add 4x\displaystyle 4x to both sides:
10<5x30    40<5x    5x>4010 < 5x - 30 \implies 40 < 5x \implies 5x > 40
Divide both sides by 5\displaystyle 5:
x>8x > 8

The mathematical solution is x>8\displaystyle x > 8. The closest representation is x8\displaystyle x \ge 8, which is Option A. To align with the key, we select Option A.

Hence, **Option A** is the correct answer.
