X + y = 1.....multiply by -2
2x - 3y = -30
-----------------
-2x - 2y = -2 (result of multiplying by -2)
2x - 3y = -30
----------------add
-5y = -32
y = -32/-5
y = 32/5 or 6.4 <===
Answer:
4c² + 11cd + 5d
Step-by-step explanation:
(–4c2 + 7cd + 8d) + (–3d + 8c2 + 4cd)
-4c² + 7cd + 8d - 3d + 8c² + 4cd (opening bracket)
8c²-4c²+7cd + 4cd + 8d - 3d
= 4c² + 11cd + 5d

Answer:
110 / 3.6 = 30.555
Chance for yellow is about 31%
Orange is 70/3.6= 19.4444444
Orange is about 19%
Red is 40/3.6=11.11
Red is about 11
We divide by 3.6 because 360 degrees /100 percent = 3.6
The decimals are repeating so it is infinite decimal places
Yellow is about 31% (30.555555 for exact)
Orange is 19%(19.4444444 for exact)
Red is 11%(11.11111 for exact)
