Framing/writing linear inequalities in one variable

Mrs. Daise is less than 100 years old. Which inequality would we use to show this? (use "a" for age)

• a > 100

• a < 100

• a > 100

• a < 100

The temperature for the day starts at 37 degrees and rises to at least 60 degrees.

Which of the following inequalities could be used to find all the possible values of t, the amount the temperature could rise?

• 37 + x > 60

• 37 + x ≥ 60

• 37 + x < 60

• 37 + x ≤ 60

Define the variable, write the inequality, solve, and label your answer.

Gabe bought two video games that cost $95 or less. One game cost $43. What did Gabe pay for the second video game?

• c for cost of second video game

  c + 43 ≤ 95

  c ≤ 52

  The cost for the second video game was $52 or less.

• c for cost of second video game

  c - 43 ≤ 95

  c ≤ 138

  The cost for the second video game was $138 or less.

• c for cost of second video game

  43 + c < 95

  c < 52

  The cost for the second video game was less than $52.
