15. x + x + 2

16. x + x + 2

17. 0.05x

18. First investment = x; second investment = $20,000 - x

19. D = 3x

20. D = (2x/3)

21. x + 20

22. 3x

23. x/8

24. 4x

25. 3 = 4 + x

You say?

some corrections:

15. x , x + 2

16. 2n + 1, 2n + 3

19. D = 3h*x(mil/h)=3x mil

20. D = (2x/3)mil

some corrections:

15. x , x + 2

16. 2n + 1, 2n + 3

19. D = 3h*x(mil/h)=3x mil

20. D = (2x/3)mil

What is mil?

 

[MathLover1]

What is mil?

miles

 

[nycmathguy]

miles

The book does not include miles with the answer. Also, there is something wrong with the site. Ithasbern extremely slow for some reason.

 

[MathLover1]

if you need to find distance (D) , given time 3 hours and speed x mph you need to use it

 

[nycmathguy]

if you need to find distance (D) , given time 3 hours and speed x mph you need to use it

I will double-check the book.

I am wondering why, in problem 16 you want to specifically make it clear that the numbers are odd but in problem 15 you do not specifically make it clear that the numbers are even.

I would say that in problem 15, with the understanding that x is even, x, x+ 2 is a correct answer and that in problem 16, with the understanding that x is odd, x, x+ 2 is also a correct answer!

Or you could answer 15 with "2n, 2n+ 2" and 16 with "2n+ 1, 2n+ 3".

But I would expect you to be consistent.
