Answer:
9x - 45
Step-by-step explanation:
To simplify this expression, we need to use Distributive Property to get rid of the parentheses. So, we multiply the -9 by everything inside the parentheses.
-9(-x + 5)
-9 · -x = 9x
-9 · 5 = -45
Now we add our products together.
9x + -45
Since there is a '+' sign and a '-' sign next to each other, we can simplify it to just a '-'.
9x - 45

Explanation:
Any situation in which 40 items are divided into 8 or 5 divisions will be modeled by an equation of this sort. A couple of possibilities are ...
- "There are 40 in all, and 8 in each group. How many groups are there?"
- "There are 40 in all, divided into 8 groups. How many are in each group?"
__
The "items" could be any sort of units of measure: beads, people, tickets, feet, yards, square miles, cubic millimeters, stars in the sky, whatever. The idea is that grouping by 8 or 5 gives you 5 or 8 groups, respectively.
