working with formulas
summary
the content provides a comprehensive guide on how to approach formula-based questions on the act exam, focusing on understanding and applying given formulas without the need for outside knowledge.
- the act test presents real-world formulas from various domains, explaining their components for solving questions.
- three primary types of questions include plug-in and solve, solving algebraically for a variable, and proportional reasoning questions.
- for plug-in questions, numbers are given to solve for other variables using the formula provided.
- solving for a variable involves manipulating the formula algebraically to isolate the desired variable.
- proportional reasoning questions explore the relationship between variables when certain quantities are scaled up or down.
- using simple numbers and ratios can simplify the process of solving proportional reasoning questions.
