We have two equations d=55t and d=20g
The left sides of this equations are the same than the right sides are equal too
a) 55t=20g
b) g=(55/20)t
c) t=6h => g=(55/20) *6 = 165/10=16.5 gallons
d= 55t= 55*6=330 miles or d=20g=20*16.5=330 miles
Good luck!!!

Based on the given values above, if you purchase a new sports car 40 years ago at a cost of <span>$5,167.55 and sold it for $97,500, this would mean that the annual rate of return you earned on the vehicle is 5%. Hope this answers your question. Have a great day!</span>
Answer:
The explicit formula is Tn = 18[(2/3)^(n-1)]
Where n is the term we are looking for
Step-by-step explanation:
Here, we want to get an explicit formula to model the equation
Now, F(2) = 2/3 * f1 = 2/3 * 18 = 12
F(3) = 2/3 * f(2) = 2/3 * 12 = 8
F(4) = 2/3 * F(3) = 2/3 * 8 = 16/3
F(5) = 2/3 * 16/3 = 32/9
Thus, seeing how the equations are progressing, we can definitely see a pattern.
That is Tn = (2/3)^(n-1)(18)
Answer:
x =±sqrt(225) = ±15
Step-by-step explanation:
x^2 = 225
Take the square root of each side
sqrt(x^2) = ±sqrt(225)
x =±sqrt(225) = ±15
