Part A: Explain why x = 5 makes 4x − 1 ≤ 19 true but not 4x − 1 < 19. (5 points) Part B: What value from the set {6, 7, 8, 9, 10} makes the equation 5x + 2 = 47 true? Show your work.

Part A:

If x = 5 then 4x = 20

20 - 1 = 19

19 is less than or equal to 19, as represented in the first equation.  however, 19 is not less than 19, as represented by the second equation.

Part B: 9

If x = 9, then 5x = 45.

45 + 2 = 47

Hope it helps, please mark brainliest if it does <3

i dont know i just need points
