Step-by-step explanation:
As
- Exercise Plus charges a yearly fee of $75 plus $10 a month.
- Gym and Swim charges a yearly fee of $50 plus $15 a month.
Let
by the number of months
![75+10x=50+15x](https://tex.z-dn.net/?f=75%2B10x%3D50%2B15x)
![10x=15x-25](https://tex.z-dn.net/?f=10x%3D15x-25)
![-5x=-25](https://tex.z-dn.net/?f=-5x%3D-25)
![\frac{-5x}{-5}=\frac{-25}{-5}](https://tex.z-dn.net/?f=%5Cfrac%7B-5x%7D%7B-5%7D%3D%5Cfrac%7B-25%7D%7B-5%7D)
![x=5](https://tex.z-dn.net/?f=x%3D5)
Therefore, 5 months will be the same cost at each gym.

good luck
86 Naira; divide 1075 by 12.5 (hopefully this is correct!)
Answer:
12.33
Step-by-step explanation:
6x - 2 + 9x - 3 = 180° (linear pair)
6x + 9x - 2 - 3 = 180°
15x - 5 = 180°
15x = 180 + 5
15x = 185
x = 185/15
x = 12.33
hope this helps you!
