Answer:
y = 12-(61) is the answer !!
It has a rotational symmetry of 6
So minimum number of degrees = 360 / 6
= 60 degrees
Let x be the month on which the fee for two plans are equal.
Therefore,
150 + 10x = 50 + 30x
10x - 30x = 50 - 150
-20x = -100
x = 5
Cumulative cost = 150 + 10(5)
= 150 + 50
= 200
Hence, Karan will pay a cumulative cost of $200 dollars with either plan to go to the gym for 5 months.
Answer:
`18. x=9
19. x=4
20. x=25,5
21. x=3
22. x=3,5
23. x=10
Step-by-step explanation:
The answer is 15.
30% of 60 = 18
45% of 60 = 27
27 + 18 = 45
60 - 45 = 15
