Answer:
2x-7 or 7-2w
Step-by-step explanation:
Y-x=3
-y-4x=2 (I multiplied this equation by -1 so when I add I can eliminate a variable.)
Now add them together.
-5x=5
x=-1 now plug in x to solve for y
-y-4(-1)=2
y=2 so your answer is (-1,2)
Answer:
216°
Step-by-step explanation:
The ratio of the sum of smallest and largest to the total of all angles is ...
(9 +15)/(9 +10 +12 +14 +15) = 24/60 = 0.4
__
The total of all angles in an n-gon is 180°(n -2), so the total of all angles in a pentagon is ...
180°(5 -2) = 540°
Then the sum of smallest and largest angles is ...
0.4(540°) = 216°
