- {x | x < 8}
- Divide each term by 3 and simplify.
- x - 2 < 6
- Move all terms not containing x to the right side of the inequality.
We have to know the angle that is not labelled. (lets call it y)
9x + y= 180
and the sum of the angles of a triangle is 180
5x + (9+x) + y=180
2 simultaneous equations

The correct ois D. -17.5 degrees
Step-by-step explanation:
The daytime temperature in Apple Valley is
falling by 2.5 degrees each day
Therefore, Change in the temperature each day
=-2.5 degrees
Now, we need to find the net change in the daily
temperature after one calendar week
Now, number of days in one calendar week = 7
So, Net change in the daily temperature after
one calendar week = Daily change × Number of
days in one calendar week
Net change in the daily temperature after
one calendar week =-2.5 x7
# Net change in the daily temperature after
one calendar week =-17.5 degrees
Therefore, The correct option is -17.5
degrees
