Dilations: find the coordinates

Dilations: find the coordinates

What you'll learn

  • Identify whether a given decimal value is a solution to a one-step inequality involving multiplication with decimals.
  • Solve one-step inequalities involving multiplication with decimals, representing the solution set on a number line with at least 80% accuracy.
  • Explain the effect of multiplying both sides of an inequality by a decimal number greater than zero, using mathematical vocabulary like 'solution set' and 'greater than or equal to'.
  • Apply the concept of inequalities with decimal multiplication to solve real-world problems, like determining the maximum number of items that can be purchased within a given budget, with at least 70% accuracy.
