Oceanside Bike Rental Shop charges 17 dollars plus 7 dollars an hour for renting a bike. Mike paid 66 dollars to rent a bike. How many hours did he pay to have the bike checked out ?

  7 hours

Step-by-step explanation:

The hourly charge was $66 -17 = $49. That charge was $7/hour so Mike had the bike for ...

  $49/($7/hour) = 7 hours.

You could write an equation for the total charge, then set it equal to 66 and find the solution that way. For h hours, the charge is ...

  charge = 17 + 7h

  66 = 17 +7h

  49 = 7h . . . . . . . . maybe this looks familiar

  49/7 = h = 7 . . . . divide by the coefficient of h

Mike had the bike for 7 hours.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
