Answer:
5x+4
Step-by-step explanation:
use the equation mx+b I think this is right but I really dunno
 
        
             
        
        
        
If 1/6 of the pan was left and there were 2 pieces left you just need to set 1/6 equal to 2/some number, this allows you to say that 1/6=2/x --> x/6=2-->x=12.
My explanation might be a little poor since this becomes fairly fundamental later on but hopefully it helps.
        
             
        
        
        
Answer:
cos ∅ = 80/89
Step-by-step explanation:
As required from the question the picture below represent a triangle UVW . The angle W = 90°. The sides WV = 39 , VU = 89 and UW = 80. The triangle forms a right angle triangle . 
Such triangle one can establish trigonometric relationship using the SOHCAHTOA principle. 
The question requested us to find the ratio that represent the cosine of  ∠U. 
The ∠U is represented as ∅ . 
Therefore,
cos ∅ = adjacent/hypotenuse
adjacent = 80. The adjacent side is the non hypotenuse side that is next to the given angle.
hypotenuse = 89 . Hypotenuse is the longest side of a right angle triangle and it opposite the right angle.  
cos ∅ = adjacent/hypotenuse
cos ∅ = 80/89
 
 
        
             
        
        
        
The inequality that represents the number of right answers (r) and wrong answers (w) Olga can give to win the contest is:  
<u><em>Explanation</em></u>
Number of right answers is  
 and number of wrong answers is  
Olga earns 12 points for each right answer and loses 4 points for each wrong answer.
So, total points earned for 
 right answers 
 
and total points lost for 
 wrong answers 
That means, <u>her score will be</u>:  
 points.
In order to win the quiz contest, Olga must score <u>more than 400 points</u>. So, the inequality will be.......
