Answer:
10 cm³
Step-by-step explanation:
The equation for density is: d = m/v, where d is the density, m is the mass, and v is the volume.
Here, d = 2.5 and m = 25.0, so plug these into the equation to solve for v:
d = m/v
2.5 = 25/v
Multiply both sides by v:
2.5v = 25
Divide by 2.5:
v = 25/2.5 = 10
Thus, the volume is 10 cm³.
 
        
             
        
        
        
Ok so it would be 3/4 times 20 
And you would get 15 
I would draw a circle that adds up to 100 
To do this multiply the 20 five times to get 100 
Then multiply the 15 by the same number (5) to get 75
Draw a circle and shade in 75% of it and that is your answer
        
             
        
        
        
Answer:
Value : c = ad - b
Step-by-step explanation:
Given the equation:  Solve for c;
Multiply both sides by d in we get;
subtract b from both sides we have;
Simplify:
ad - b = c
Therefore, the value of c is, ad -b
