Step-by-step explanation:
Answer:
Whoa, that's a lot to answer...
15. 30000=500x
16. y=58x+5
in 16, the total cost is y, so y has to be in 1 side for itself. and we need to add the amount of tickets and the fee (5$). So we get that equation.
Answer:185 m , 60 m
Step-by-step explanation:
Given
Length is 5 m more than 6 times its width
Suppose width is ![x](https://tex.z-dn.net/?f=x)
So, length is given by ![6x+5](https://tex.z-dn.net/?f=6x%2B5)
The area is given by ![l\times b](https://tex.z-dn.net/?f=l%5Ctimes%20b)
Put values of length and width
![\Rightarrow (6x+5)x=5550\\\Rightarrow 6x^2+5x-5550=0\\](https://tex.z-dn.net/?f=%5CRightarrow%20%286x%2B5%29x%3D5550%5C%5C%5CRightarrow%206x%5E2%2B5x-5550%3D0%5C%5C)
On solving the quadratic equation, we get ![x=30](https://tex.z-dn.net/?f=x%3D30)
Length is ![6\times 30+5=185\ m](https://tex.z-dn.net/?f=6%5Ctimes%2030%2B5%3D185%5C%20m)
Width is ![x=30\ m](https://tex.z-dn.net/?f=x%3D30%5C%20m)
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
