Answer:
the angles are 120.1 and 59.9
Step-by-step explanation:
supplementary means that the add up to be 180
I made a system of equations and to make thing faster I graphed them but if you wanted you could solve fully
x+y=180
y-60.2=x
19 - 2(x - 7)
First, expand to remove the parentheses. / Your problem should look like: 19 - 2x 14
Second, simplify. / Your problem should look like: -2x + 33
Answer: -2x + 33
This is the same as averaging. You add them and divide by 2.
((m/n) + (p/q))/2 would be a number in between m/n and p/q.
Do note that n and q must be nonzero, but luckily that is a given.
I accidentally went too far, but I still solved your question... the answer is 9x^2 - 6x
All are correct except C
You need to check: A, B and D
Hope it helps.
