Solving Real-World Inequalities

The video tutorial explains how to write inequalities based on given scenarios. It covers three examples: comparing Eric's height to Preethi's, determining the temperatures at which Sydney wears skirts, and comparing Haley's race time to Lola's. Each example involves understanding the relationship between variables and expressing it as an inequality.

• Cannot be determined

• Eric

• Preethi

• Both are the same height

What does it mean if Haley finishes after Lola?

• Haley's time is less than Lola's time

• Haley's time is equal to Lola's time

• Haley's time is more than Lola's time

• Haley's time is not comparable to Lola's time
