Step-by-step explanation:

An inequality is when two expressions are not equal and the relationship could be greater than or less than. In this case, the sign > indicates that the expression 1/2+k is higher than 18. So, the phrases that can be used to represent this are the ones that contain the words more than, greater than and above that convey the meaning that the sum of one-half and a number is higher than 18.

Step-by-step explanation:

MORE THEN IMPLIES + SIGN. SO NO

GREATER THAN IMPLIES AN INEQUALITY. SO YES

BELOW ALSO IMPLIES AN INEQUALITY BUT THE SIGN IS > NOT <. SO NO

ABOVE EIGHTEEN CAN WORK (NEVER HEARD IT PHRASED THIS WAY). SO YES

LESS THAN EIGHTEEN IS NO BECAUSE WE WANT GREATER THEN EIGHTEEN. SO NO
