Hello :
sum of complementary angles is : 90°
(4x)°+( 5x - 18)° = 90°
(9x)° = 108°
x° = 12°
the angles are : 48° and : 42° ( subsct x= 12° in (4x)° , ( 5x - 18)° )
Let the number of hours the ski jet was rented be x, then
For company A, Cost = 2.25x + 24
For company B, Cost = 2.75x + 23
Fro the cost to be the same: 2.25x + 24 = 2.75x + 23
2.75x - 2.25x = 24 - 23
0.5x = 1
x = 1/0.5 = 2
x = 2
The cost are the same after 2 hours.
