INSTRUCTIONS Griffin uses a courier service that charges $18.50 plus $0.25 per mile for each delivery. The courier’s fee for a delivery was $45.75. Griffin wrote this equation using x as the number of miles: 18.50 + 0.25x = 45.75.

Solve the equation to find the number of miles the courier drove.

Put the steps in order to solve the problem. Then solve.

(Please help!!)

x=109

Step-by-step explanation:

18.50 + 0.25x = 45.75

-18.50.               -18.50

0.25x=27.25

/0.25.  /0.25

x=109

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
