3/4…
To simplify a fraction, you have to find a similar factor between the numerator and denominator. In this case, it would be 4.
You would divide both numbers by this common factor and create a new fraction.
So… 9/3=3, and 12/3=4. When combined, the answer becomes 3/4.
        
             
        
        
        
Step-by-step explanation:
I'll do the first problem as an example.
∠P and ∠H both have one mark.  That means they're congruent.
∠T and ∠G both have two marks.  So they're congruent.
∠W and ∠D both have three marks.  So they're congruent.
So we can write a congruence statement:
ΔPTW ≅ ΔHGD
We can write more congruence statements by rearranging the letter, provided that corresponding pairs have the same position (P is in the same place as H, etc.).  For example:
ΔWPT ≅ ΔDHG
ΔTWP ≅ ΔGDH
 
        
             
        
        
        
(12,200 + 16,211 + 12,050 + 11,350 + 13,325) / 5 = 65136/5 = 
13027.2 <== this is the mean (average)
11,350 , 12,050 , 12,200 , 13,325, 16,211
median (middle number) = 12,200
there is no mode...a mode is a number that appears most often...all the numbers appear once in this data.

-x + 4 + 20x = 156
 19x + 4 = 156
 - 4. -4
 19x = 152
 19. 19
 X = 8
