(5 | -2) should be the solution of the equations
So it workt for c)
c)
3*(5) - 5*(-2) = 25
(5) + 5*(-2) = -5
Event 4 (impossible), Event 3 (probability is 7/20), Event 1 (probability is 6/12 which is greater than 7/20), and Event 2 (certain to happen)
Answer:
Step-by-step explanation:
1. Combine Like Terms
24 + 6a = 6 - 4a
+4a +4a
24 + 10a = 6
-24 -24
10a = -18
___ ___
10 10
a= -1.8
