The exact form is 7/10
Decimal for is 0.7
The measure of its supplementary angle is 42 degrees
The sum of supplementary angle is qual to 180 degrees
Let the required angle be x
The sum of the supplements of 138 degrees will be expressed as:
x + 138 = 180
x= 180 - 138
x = 42 degrees
Hence the measure of its supplementary angle is 42 degrees

There are 12 more paintings because 1/6 of 24 equals 4 and 2/3 of 24 equals 16. So then, you subtract 4 and 16 to get 12.
Combine like terms:
-r-10r
We can always add variables as long as they are the same. So we can not add 10x+20y. That's impossible.
We can't add 3r^2+10r. That's also impossible.
However, we have the same variable, r. So we can add -r-10r. And the answer is:
-11r
Hope this helps! :)
