Question

how can you express and solve real - world and mathematical problems with numerical and algebraic expressions, equations, and inequalities?

Explanation:

First, identify the key - elements in the problem and assign variables to represent unknowns. Then, translate real - world or mathematical relationships into numerical or algebraic expressions, equations, or inequalities. For equations, use inverse operations to isolate the variable and find the solution. For inequalities, follow similar rules but consider the direction of the inequality when performing operations.

Answer:

Identify variables, translate relationships, solve equations/inequalities using operations.
