For this case, the first thing we must do is define a variable.
 We have then:
 x: number of weeks
 y: amount of cereal that Melanie eats
 We now write the function that models the problem: 

 Then, for 5 weeks we have: 
 Answer:
 Answer:
 A model that best represents the number of pounds of cereal she eats is:
  For 5 weeks we have:
 For 5 weeks we have:
  
 
        
        
        
100 percent because 45 % is always in between 30 and 50 %
        
             
        
        
        
The expression can represent the value of x in terms of R, m, n and k after rearranging.
<h3>What is an expression?</h3>
It is defined as the combination of constants and variables with mathematical operators.
It is given that:
The expression is:

Square both side:

16m² x n = R²k³
x = (R²k³)/(16m²n)
The above expression represents the value of x in terms of R, m, n and k.
Thus, the expression can represent the value of x in terms of R, m, n and k after rearranging.

Answer:
27 inches
Step-by-step explanation:
2ft and 3 in how much inches
There are 12 inches in a foot
Since we have 2 feet we multiple 12 x 2
This gives us 24 inches
But we also have 3 extra inches
24 + 3 = 27 inches
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
1.5x - 15 dollars = x - 20    Add 15 to both sides.
1.5x - 15 + 15 = x - 20 + 15
1.5x = x - 5                          They will never coincide.
1.5x-x = - 5
0.5x = - 5                            Multiply by 2
x = - 10
