Since supplementary angles are angles that equal to 180, you first need to subtract 40 from 180 to find out what the equation equals. This is the layout of the equation. 140=4x+20. Next you subtract 20 from each side, 120=4x then you divide by 4 four, x=30.
Answer:
P(-A) = 0.388
Step-by-step explanation:
By the <u> PROBABILITY POSTULATE: </u>
P(A) + P(not A) = 1
Here, P(A) = 0.612
So, P(not A) = P(-A) = 1 - 0.612 = 0.388
⇒P(-A) = 0.388

The combined amount of cats sold is 117.
Ratio expresses the relationship between two variables. It shows the frequency of which that one value is contained within another variable.
The ratio of Siamese cats to house cats = 4 : 9
Number of Siamese cats = 36
Number of combined cats = c
This equation can be formed using the above information:
4/13 x c = 36
4c = 468
c = 468 / 4
c = 117
