Which sentence represents m > 41?

• Mary’s points, m, totaled more than 41
• Calvin ran no less than 41 miles, m
• The temperature, m, was less than 41°F
• The magazines’ cost, m, was not more than $41.

m - 9 ≤ 20

• By adding 20 to both sides
• By subtracting 9 to both sides
• By adding 9 to both sides
• By subtracting 20 to both sides

28 > m - 4

• m < 32
• m > 32
• m < 24
• m > 24
