Answer:
You have to replace x for each density
Step-by-step explanation:
Density = Mass / Volumen
1,000 g = 1 kg
1,000,000 cm^3 = 1 m^3
g/cm^3 = 1000 kg/m^3
Using density as x
![volumen \: = \frac{50000}{x} \\ volumen \: sphere \: = 4\pi {r}^{3} \\ 4\pi {r}^{3} = \frac{50000}{x} \\ r = \sqrt[3]{ \frac{50000}{4\pi {x}^{} } }](https://tex.z-dn.net/?f=volumen%20%5C%3A%20%20%3D%20%20%5Cfrac%7B50000%7D%7Bx%7D%20%20%5C%5C%20volumen%20%20%5C%3A%20sphere%20%5C%3A%20%20%3D%204%5Cpi%20%7Br%7D%5E%7B3%7D%20%20%5C%5C%204%5Cpi%20%7Br%7D%5E%7B3%7D%20%20%3D%20%20%5Cfrac%7B50000%7D%7Bx%7D%20%20%5C%5C%20r%20%3D%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B50000%7D%7B4%5Cpi%20%7Bx%7D%5E%7B%7D%20%7D%20%7D%20)
Answer: it will take 6 months for both gyms to cost the same.
Step-by-step explanation:
Let m represent the number of months that it will take for the cost of both gyms be the same.
At one gym, there is a $12 start-up fee, and after that each month, m, at the gym costs $20. This means that the total cost for m months is
12 + 20m
At another gym, each month at the gym costs $22. This means that the total cost for m months is 22m
For both costs to be the same, the number of months would be
12 + 20m = 22m
22m - 20m = 12
2m = 12
m = 12/2 = 6
(x-5) (x+5) because if you times the two xs you'll get x squared and if you times negative 5 and positive 5, you'll get negative 25!!
Hope this helps!!!
