Answer:
Can you show a picture of the diagram?
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.
Hope this helps!

Step-by-step explanation:
1 foot = .3048 meters
Lake Baikal: 5369 ft. = 1636.4712 m
Great Slave Lake: 2015 ft. = 614.172 m
Quesnel Lake: 506 m
Quesnel Lake:Lake Baikal

Quesnel Lake:Great Slave Lake

Answer
the answer is -56
Step-by-step explanation:
When you add up all the angles, it would be equal to 180 degrees.
Since angles 2 and 3 are congruent, angle 3 is also equal to 6x + 24.
We know also that angles 3 and 4 are complementary, so (6x+24) + 5x = 90.
Let's find x.
6x+24+5x = 90
11x = 90-24
11x = 66
x = 6
Angle 2 and 3 are 6(6) + 24 = 60 degrees
Angle 4 is 5(6) = 30 degrees
180 - 60 - 60 - 30 = 30 degrees
Angle 1 is equal to 30 degrees :D :D
