Sandra rode her bike 54 miles in one day. She rode 6 times the number of miles Caleb rode his bike. How many miles did Caleb ride
his bike? Let b represent the number of miles Caleb rode his bike.
Ab 54 - 6
B 546 = 6
C 6 = 54

54 = 6b

Step-by-step explanation:

Sandra rode her bike 54 miles in one day.

She rode 6 times the  number of miles Caleb rode his bike.

Let Caleb rode b miles. It means,

54 = 6b

We can also find b as follows :

b = (54/6)

b = 9 miles

Hence, the required equation is "54 = 6b".

step-by-step explanation:

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.
