A family buys 5 airline tickets and travel insurance that costs $17 per ticket. The total cost is $945. Let x represent the price of one ticket. Write an equation to represent this situation. What is the price of one ticket? Middle school

Step-by-step explanation:

We know:

5 tickets are purchased

Insurance = $17

Total = $945

x = price of 1 ticket

5x would be the total cost of the tickets, and $17 insurance is a one time charge, everything together equals $945, so our equation is:

5x + 17 = 945

Solve for x to find the price of each ticket.

5x + 17 = 945  Subtract 17 from each side

5x + 17 - 17 = 945 - 17

5x = 945 - 17

5x = 928    Divide each side by 5

5x/5 = 928/5

x = 928/5

x = $185.60

One ticket costs $185.60

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.
