- Part A: Explain why x = 5 makes 4x - 13 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 (5 points)
​

Answer 1

Part A is ≤ means less than OR equal to. < only means less than

Part B is 9

Explanation:

A: Because it would equal 19, and 19 is equal than 19. 4(5) - 1 would equal 19, which is equal to 19, and not less than. ≤ means less than or equal to. < means less than. So its not true.

B: 47 - 2, 45. Then 5 x 9 equals 45. So 5 x 9 equals 45, then add 2 would equal 47.
