Answer:
137°
Step-by-step explanation:
So, both are equal to each other due to them being the same degree angle.
5x + 7 = 8x - 71
subtract 5x on both sides
7 = 3x - 71
add 71 to both sides
7 + 71 = 3x - 71 + 71
78=3x
divide both sides by 3
78/3 = x
x = 26
insert x into the equations
5(26)+7°
= 137°
8(26)-71°
= 37°

Step-by-step explanation:
T= # of rental hours
Multiply number of hours rented by the cost per hour, add that total to the reservation fee. The total needs to be less than $91.
Reservation + ($ per hr * # hrs) < $91
$19 + $6t < $91
subtract 19 from both sides
6t < 72
divide both sides by 6
t < 12
ANSWER: To spend less than $91, they need to rent the room less than 12 hours.
Hope this helps! :)
