Final answer:
For equations with infinite solutions, look for scenarios where simplifying the equation gives a true statement like 0=0. The fifth step in finding and approximating irrational numbers involves making a list of the known information from the problem.
Step-by-step explanation:
The hints section for equations with infinite solutions typically advises that you should look for scenarios where after simplifying the equation, you end up with a statement that is always true, such as 0=0. This indicates that the original equation is valid for all real numbers, hence it has an infinite number of solutions.
Concerning the Process for finding and approximating Irrational Numbers, the fifth step involves making a list of what is given or can be inferred from the problem as stated (identify the knowns). This step is crucial as it provides a clear picture of the data you have at your disposal to work with, which is necessary before you can proceed to solving the equation or finding the value of an unknown.
