Example: Translating and Solving 'Twenty-seven less than xx is at least 48'

To translate and solve the sentence "Twenty-seven less than xx is at least 48," apply a step-by-step translation process:

  1. Translate the left side: The phrase "Twenty-seven less than xx" indicates subtraction from xx, giving the expression x27x - 27.
  2. Translate the inequality: The phrase "is at least" signifies a minimum limit, which corresponds to the "greater than or equal to" symbol, \geq.

Combining these elements generates the inequality x2748x - 27 \geq 48.

To solve the inequality, isolate xx by applying the Addition Property of Inequality—add 2727 to both sides: x27+2748+27x - 27 + 27 \geq 48 + 27 x75x \geq 75

To represent the solution set visually on a number line, a left bracket is placed at 7575 to indicate it is included, and shading continues to the right. In interval notation, this is expressed as [75,)[75, \infty).
