Answer:
Let width of rectangle be x cm.
3x+x+3x+x=39
 8x=39
 x=39÷8
 =39/8
 =4/7/8
 3x=39/8×3
 =117/8
 =14/5/8
Hence, length=14/5/8cm while width=4/7/8cm.
 
        
             
        
        
        
Hey there! :)
Answer:
p(x) = 6x - 15
Step-by-step explanation:
If p(x) = r(x) - c(x), subtract the two equations. Therefore:
p(x) = 10x - (4x + 15)
p(x) = 10x - 4x - 15
Combine like terms and simplify:
p(x) = 6x - 15
 
        
                    
             
        
        
        
Set up a system of equations.
0.10d + 0.25q = 39.25
d + q = 250
Where 'd' represents the number of dimes, and 'q' represents the number of quarters.
d + q = 250
Subtract 'q' to both sides:
d = -q + 250
Plug in '-q + 250' for 'd' in the 1st equation:
0.10(-q + 250) + 0.25q = 39.25
Distribute 0.10:
-0.10q + 25 + 0.25q = 39.25
Combine like terms:
0.15q + 25 = 39.25
Subtract 25 to both sides:
0.15q = 14.25
Divide 0.15 to both sides:
q = 95
Now plug this into any of the two equations to find 'd':
d + q = 250
d + 95 = 250
Subtract 95 to both sides:
d = 155
So there are 95 quarters and 155 dimes.
