|AC| = 2|DE|
⇒
4x - 2 = 2(x + 6) = 2x + 12
2x = 14
x = 7
⇒
|AC| = 26
You subtract 16 from 50
so 50-16=34
so your answer is 34 degree
Multiply 0.57 by 51
=29.07

T= # of rental hours
Reservation Fee= $31
Per Hour Fee= $7.40
Multiply number of hours rented by the cost per hour, add that total to the reservation fee. The total needs to be less than $97.60.
Res Fee + ($ per hr * # hrs) < $97.60
$31 + $7.40t < $97.60
subtract 31 from both sides
7.40t < 66.60
divide both sides by 7.40
t < 9
ANSWER: To spend less than $97.60, they need to rent the room less than 9 hours.
Hope this helps! :)
