Answer:The value of the expression increases as r decreases.
Step-by-step explanation:
To find : What happens to the value of the expression as r decreases?
Given Expression: 80-2r
We check for different value of r as decreasing order,
r 80-2r
5 80-10=70
4 80-8=72
3 80-6=74
2 80-4=76
1 80-2=78
As r decreases the value of expression increases.
Therefore, the value of the expression increases as r decreases.

Answer:
If I read your problem write: 126
Step-by-step explanation:
if I interpret this as
- (-3)* 2 * (5) * 2 * (7) * 3 divided by 5 * 2
we can get 126
because:
- (-3)* 2 * (5) * 2 * (7) * 3 divided by 5 * 2
= 6 * 5 * 2 *7 * 3 / (5*2)
= 60*7 * 3/ (5*2)
= 420 * 3 / 10
= 1260/10
= 126
