45 + 35x = 40x
45 = 40x - 35x
45 = 5x
45/5 = x
9 = x <=== they are the same cost at 9 nights

Answer:
4 hours and 30 minutes.
Step-by-step explanation:
660 miles = 1 hour
1320 miles = 2 hours
1980 miles = 3 hours
2640 miles = 4 hours
There are only 330 miles left and that is half of 660mph so therefore it would only take half an hour for these last 330 miles.
So we know that it will be taking 4 hours, you would then add the 30 minutes which gives you 4 hours and 30 minutes.
Hope this helps!
Answer:
Area of equilateral triangle = 81√3 cm²
Step-by-step explanation:
Given:
Perimeter of an equilateral triangle = 54 cm
Find:
Area of equilateral triangle
Computation:
Perimeter of an equilateral triangle = 3 x Side
54 = 3 x Side
Side of equilateral triangle = 54 / 3
Side of equilateral triangle = 18 cm
Area of equilateral triangle = [√3/4]side²
Area of equilateral triangle = [√3/4][18]²
Area of equilateral triangle = [√3/4][324]
Area of equilateral triangle = [√3][81]
Area of equilateral triangle = 81√3 cm²
