2 or 3 I think is the answer for number 5
Answer:
Step-by-step explanation:
Choice A
Log 10 = 1.
So A is actually right, although it does not look it.
log(20 * x^5 ) - 1 is correct.
Choice B
Log(x^5 * 20 / 10)
log(2 x^5)
Choice B is also correct
Choice C is not correct, or if it is, I don't know how to get it. You need the 20 in there somewhere.
No! Dis not correct. The 2 is not raised to the 5th power.
And E is not correct. I'm not sure how they got it. Even + 1 is not correct. It should be -1 if that is how it is to be done.
This isnt 30 points this is 15
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
