Answer:
The equivalent expression is - 25n - 2 and it matches with option D.
Step-by-step explanation:
We have to simplify and create the equivalent expression for
{- 2(- 5n + 6) + 5(2 - 7n)}
Now, {- 2(- 5n + 6) + 5(2 - 7n)}
= 10n - 12 + 10 - 35n
= - 25n - 2
Therefore, the equivalent expression is - 25n - 2 and it matches with option D. (Answer)

Step-by-step explanation: im not stoopid
By setting up a system of equations we can easily solve this problem. Let's denote Jane's working hours with x and Jack's working hours with y. Since they don't want to work more than 65 hours, the first equation is x+y=65. The second equation is 14x+7y=770. By solving this system of equation , we find that y=20 hours, which is Jack's maximum working hours.
