Answer 1

Answer:

11. (x-2)/(x+8)

12. 9+t

13. h = 2A/b

Step-by-step explanation:

11. Since x is used to represent the number, 2 less than a number is x-2. 8 more than a number is x+8. The quotient of the first and second of these is the first one divided by the second one:

... (x -2)/(x +8) . . . . . parentheses are required unless the expression is typeset:

$\dfrac{x-2}{x+8}$

12. Apparently, we're to assume the salesman keeps on driving. If he had any sense (or a good union), he would stop after 9 hours. t hours added to 9 is ...

... 9 + t

13. Divide by the coefficient of h.

... h = A/((1/2)b) = 2A/b
