A pound of oranges cost x dollar => A pound of pears cost x+3 dollar
We have: 8x+4(x+3)=30 => 12x=30-12=18 =>x=1.5
5 pounds of pears cost: 5(x+3)=5(1.5+3)=5*4.5= 22.5 (dollar)
 
        
             
        
        
        
The answer is a = 0, b = -5, and c= 39.
<u>Step-by-step explanation</u>:
<u>step 1</u> : 
A quadratic equation means that it should have at least one squared term. 
<u>step 2</u> : 
The standard form is ax² + bx + c = 0. 
<u>step 3</u> : 
The solution to the quadratic equation is usually written in the form 
x = (-b ± √(b2 − 4ac))/(2a)
where a = coefficient of x^2
            b = coefficient of x
            c = constant term
<u>step 4</u> :
The given equation is -5x +32.
∴ The answer is a = coefficient of x^2 = 0
                            b = coefficient of x = -5
                            c = constant term = 39
 
        
             
        
        
        
Answer:
Le produit de la racine cubique de 5 et de X ^ prime prime en une expression algébrique: french, youre welcome.
Step-by-step explanation:
 
        
             
        
        
        
Set up equal ratios
t/6=0.75/4.5  multiply both sides by 6
t=4.5/4.5
t=1 hour
So it will take Madison one hour to ride another six miles.
