Let's say we placed dominoes close together such that they only fell over one way: to the right hand side. Let's call the dominoes A and B.
Domino A is to the left of domino B. If we push over domino A, then it will hit domino B to cause it to fall over as well. We have a mini chain reaction of sorts. The fall of A triggers the fall of B, but not the other way around.
For this problem, we can think of domino A as "Jillian gets a raise" and domino B as "she will buy a new car". The raise causes her to get a new car, but not vice versa.
Since we're told in the last sentence she definitely got the raise, this must mean she will definitely get the new car.
In terms of symbols, the law of detachment is stated as
- If P, then Q
- P is true
- Therefore Q is true
Side note: some books might use the term "modus ponens" instead of "law of detachment". They're the same thing.
One way to find
is to notice that the part on the left hand side within the parentheses can be written as a square:
So you could write
Since these two expressions are equal, and the bases are the same, you know the exponents must be equal, with the exponent on the right hand side being 1. So
, or

Answer:
92.5
Step-by-step explanation:
The total of Megan's scores is ...
94 +81 +87 +93 = 355
so her current average is 355/4 = 88.75
The score (s) Megan needs for a 90 average is ...
(2/3)(88.75) +(1/3)s = 90
2(88.75) +s = 270 . . . . . . . . multiply by 3
s = 270 -177.5 = 92.5
Megan needs a score of 92.5 on her final to have an overall average of 90.
