Write About the Math
How much more does the detective need? How did you solve and graph this inequality?¿Cuánto más necesita la detective? ¿Cómo resolviste y graficaste esta desigualdad?
Say your answer to a partner first. Then write it, using at least two of these words:
Model: Solving an inequality gives a range of solutions, not one number. — Students note both use inverse operations to isolate the variable, but an inequality's solution is many values (a range) while an equation's is a single value.
