Riders must be at least 48 inches tall to go on the roller coaster. li's little brother is 3 feet 6 inches tall. which inequality can be used to find how many inches he must grow to be able to ride the roller coaster

Answer 1

Sample Response/Explanation: No, the work is correct, but the interpretation is not. “6 is less than or equal to h” means that h is greater than or equal to 6. He must grow at least 6 inches, not at most 6 inches.

Answer 2

Minimum height to ride roller coaster is 48 inches

Litlle brother's height is 3 feet 6 inches = 3 x 12 inches + 6inches ( 1 foot = 12 inches)

- 36 + 6 inches = 42 inches

Little brother needs to grow 48 - 42 inches = 6 inches
