Answer:
- 19 ≤ 19 . . . true
- 19 < 19 . . . false
- x = 9
Step-by-step explanation:
A) A number cannot be less than itself, but can be equal to itself.
In each case, the left side of the inequality evaluates to 19:
4(5) -1 = 20 -1 = 19
It is true that 19 is less than or equal to 19. This is true because 19 = 19.
It is not true that 19 is less than 19. A number cannot be less than itself.
