TEMPERATURE INEQUALITIES A scientist is conducting an experiment with liquids. Liquid A cannot cool more than 18°C or it will turn into a solid. The scientist begins to cool the liquid at a constant rate of 3°C per hour. X- Write an linequality to represent, t, the number of hours the scientist can cool Liquid A without changing its state of matter. --- 300 * 15 43 51 18 °C 1 b. Use concrete or pictorial models to find the number of hours the scientist can cool Liquid A without changing its state of matter and represent the solutions of the inequality on a number line.
