4.5 is intantly wrong because it is rational.
The probability would be 9/12 or 3/4 in the lowest form
Answer:
1/2 and 0.5 is right
Step-by-step explanation:
-2 | 8-x| - 6 = -12...add 6 to both sides
-2 |8-x| = -12 + 6
-2 |8-x| = - 6...divide both sides by -2
|8-x| = -6/-2
|8-x| = 3
8 - x = -3 -(8 - x) = -3
-x = -3-8 -8 + x = -3
-x = -11 x = -3 + 8
x = 11 x = 5
