Math Problem Statement

Which of the following are solutions to the inequality 3 ≥ a/33 + 2?

Solution

The inequality you provided is:

3a33+23 \geq \frac{a}{33} + 2

To solve this inequality, follow these steps:

  1. Isolate the variable term a33\frac{a}{33}: 32a333 - 2 \geq \frac{a}{33} 1a331 \geq \frac{a}{33}

  2. Multiply both sides by 33 to eliminate the denominator: 33×1a33 \times 1 \geq a 33a33 \geq a

    This simplifies to: a33a \leq 33

The solution to the inequality is a33a \leq 33. Now, let's check which values from the options provided are solutions:

  • a=132a = 132: This does not satisfy a33a \leq 33, so it's not a solution.
  • a=66a = 66: This does not satisfy a33a \leq 33, so it's not a solution.
  • a=99a = 99: This does not satisfy a33a \leq 33, so it's not a solution.
  • a=33a = 33: This does satisfy a33a \leq 33, so it's a solution.

Thus, the correct solution is a=33a = 33.
