Consider the inequality, × + 8 > 13
PART A: Use substitution to determine which numbers in the set (4, 4.5, 5, 5.5 ,6, 6.5) makes the inequality true.
PART B: What is the solution to the inequality.
PART C: Explain why x = 5 is not a solution to the inequality.



Answer :

MrTang
A
4+8=12  wrong
4.5+8=12.5  wrong
5+8=13  wrong
5.5+8=13.5  right
the rest of the numbers are above 5.5 so they aren't wrong
5.5, 6 and 6.5 makes the inequality true

B
x+8>13
x>13-8
x>5

C
x=5 is not a solution to the inequality because 5+8 is not more than 13.
