Bob bought 24 hockey tickets for $83. Adult tickets cost $5.50 and child tickets cost $2.00. Let x = the number of adult tickets bought and y = the number of child tickets bought. How many child tickets did he buy? What systems of equations would you use to solve this problem?

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

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.

the answer is 2/54
