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.

Who is taller, Eric or Preethi?

• Cannot be determined

• Eric

• Preethi

• Both are the same height

What is Preethi's height in centimeters?

• 155 cm

• 160 cm

• 150 cm

• 158 cm

Which inequality correctly represents Eric's height (E) compared to Preethi's height?

• E > 158

• E = 158

• E < 158

• E ≥ 158

At what temperature does Sydney wear skirts?

• Above 25°C

• Below 25°C

• Exactly 25°C

• 25°C or above

Which variable is used to denote temperature in the inequality for Sydney?

• C

• W

• T

• S

What is the inequality that describes the temperature (T) at which Sydney wears skirts?

• T > 25

• T = 25

• T < 25

• T ≤ 25

Who finishes the race first, Lola or Haley?

• Lola

• Haley

• Both finish at the same time

• Cannot be determined

How long does it take Lola to finish the race?

• 50 seconds

• 60 seconds

• 53 seconds

• 55 seconds

Which inequality correctly represents Haley's finish time (H) compared to Lola's finish time?

• H < 53

• H = 53

• H > 53

• H ≤ 53

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
