It's the first one. y = 3x
proportional means they are just some multiple of the other.

Find the measures of two angles, one positive and one negative, that are coterminal with pi divided by five. How do you do this?
Anestetic [448]
\theta= \frac{\pi}{5} 

\\ \theta_1,\theta_2 - coterminal angles

\\ \theta_1= \frac{\pi}{5} +2\pi= \frac{\pi}{5} + \frac{10\pi}{5}= \frac{11\pi}{5}  
\\
\\ \theta_2= \frac{\pi}{5} -2\pi= \frac{\pi}{5} - \frac{10\pi}{5}=- \frac{9\pi}{5}

Ok so 4*5=20
so the area is 20meters
now lets convert 200cm to m
= 200/100=2m

now 20m/2=10

Race track a has 37,000 more grandstand seats than three times the number of grandstand seats at another race track
kherson [118]

Let x represent the number of grandstand seats on race track #2

The number of grandstand seats on race track #1 =  37,000 + 3x

Total number of seats together = 289,000

So, we can frame the equation as follows:

37,000 + 3x + x = 289,000

4x + 37,000 = 289,000

4x = 289,000-37,000 = 252,000

4x = 252,000

x = 252,000/4

x = 63,000

Number of seats on race track #2= x = 63,000 seats

Number of seats on race track #1 = 37000+3x = 37000+3*63000 = 226,000 seats
