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
Answer:
Step-by-step explanation:
You need to simplify
0.10r + 0.20b = 24
3r = b + 20....b = 3r - 20
0.10r + 0.20(3r - 20) = 24
0.10r + 0.60r - 4 = 24
0.70r = 24 + 4
0.70r = 28
r = 28/0.70
r = 40 <=== there are 40 reds
0.10r + 0.20b = 24
0.10(40) + 0.20b = 24
4 + 0.20b = 24
0.20b = 24 - 4
0.20b = 20
b = 20/0.20
b = 100 <=== there are 100 blues
D. None of the above. Exponential decay implies constantly decreasing prices, i.e, f'(x) < 0 for all x.
I think the correct answer from the choices listed above is option C. <span>When you make the circle bigger or smaller, it is the radius of the standard equation for the circle centered at the origin changes. Hope this answers the question. Have a nice day.</span>
