Explanation:
An inequality that can be used to find height he must grow to be able to ride the roller coaster is 42 + h ≥ 48.
"It is a statement of an order relationship(greater than, greater than or equal to, less than, or less than or equal to) between two numbers or algebraic expressions."
For given question,
Li's little brother is 3 feet 6 inches tall.
We have been given 1 ft. = 12 in.
So, 3 ft. = 36 in.
3 feet 6 inches = 3 feet + 6 inches
= 36 inches + 6 inches
= 42 inches
This means, Li's little brother is 42 inches tall.
Let Li's little brother must grow 'h' to be able to ride the roller coaster.
Riders must be at least 48 inches tall to go on the roller coast.
so, we get an inequality,
42 + h ≥ 48
Therefore, an inequality that can be used to find height he must grow to be able to ride the roller coaster is 42 + h ≥ 48.
