Substitute x with -12
1/3(9+(-12) = 1/3(-3)
the answer is -1
14000+7x=35x (x being the number of books) solve for x and you have your answer. 14000=35x-7x=28x therefore x=14000/28=500 so he needs to sell 500 books before he breaks even.

3x-2= -6
Step-by-step explanation:
The denominator of the rational expression 600/(x-4) is x-4.
We know x represents Sarah’s average speed. So x-4 will also represents the average speed. And x-4 represents 4 mph less than the average speed of Sarah, x.
Therefore, option a) is correct.
well...
15 x 20 = 300
300+85 = 385
you can get 20 watches for $385
