These are all perfect cubes 1^3, 2^3 , 3^3 so the nth term is n^3
The next term after 64 = 5^3 = 125 answer
The answer is true hope this helps
A unit rate is basically the same as a unit cost like for example if you buy 10 dogs for 1000 dollars total then its 1000/10 and each dog is $100. since its 100 for each dog its 100/1 so the unit cost is $100
Create a system of 2 equations
Let x be daily fee and y the mileage charge, then
4x + 370y = 244.50...........(1)
3x + 190y = 161.50..............(2)
If we multiply (1) by 3 and (2) by -4 and add the 2 equations we eliminate x:-
12x + 1110y = 733.50
-12x - 760y = -646 Adding :-
350y = 87.5 so y = 0.25
Plugging y = 0.25 into eqation (1) we get 4x = 244.50 - 0.25 * 370
giving x = 38
Answer is daily fee = $38 and mileage charge = $0.25 per mile.
