Answer:
using x< 4 4/5, x is less than or equal to 4 but not including rational numbers.
Explanation:
5x-9<15
+9 +9
5x<24
÷5 ÷5
x<24/5 = x< 4 4/5
Whole numbers are numbers that don't have any fractional values so we have to drop to the next whole number (4) meaning that x is less than or equal to 4 but not including rational numbers because rational numbers have a fractional value.
(hopefully i did this right for you because the question doesn't really explain on what it wants without context)
