P-6 because you subtract the variable from the 6 
        
             
        
        
        
Answer:
D. 5/6
Step-by-step explanation:
There are 30 marbles
If you add the black, red, and green marbles together, you get 25
25/30 is equivalent to 5/6
 
        
             
        
        
        
7 x 6 = 42 x 5 = 210 x 8 = 1,680 x 4 = [ 6,720 ]
        
             
        
        
        
180 I believe because all angles in a triangles will ALWAYS add up to 180
        
             
        
        
        
The value 0.92 indicates the relative density of the ice. 
Data;
- Density = 0.92g/ml
- Specific gravity = 0.92
<h3>Specific Gravity</h3>
Specific gravity of a substance is defined as the relative density of substance. This can be further said to be the ratio between the density of a substance to the density of the reference substance.
mathematically;

The value 0.92 indicates the relative density of the ice.
