If at Worlds of Fun, a person must be at least 48 inches tall to ride the roller coasters. The inequality that determine how much he needs to grow in order to meet the height requirement is: a. 42 + x ≥ 48.
What is inequality?
We can use subtraction to represent the amount he needs to develop. His new height if he grows by a specific amount, will be 42 inches + that amount.
So, the correct inequality would be:
42 + x ≥ 48
In this inequality:
x = amount Cornelius needs to grow
His current height of 42 inches will increase by x so that the resultant height is larger than or equal to 48 inches, the minimum height needed to ride the roller coasters.
Therefore the correct option is A.
