Answer:
1995 => 22°
2005 => 36°
Step-by-step explanation:
Central angle of the sector representing nuclear energy in 1995 = percentage of nuclear energy in 1995 ÷ 100 × 360°
Nuclear energy is approximately 6% (rounded to whole number) in 1995.
Central angle = 

Central angle representing nuclear energy in 1995 ≈ 22° (nearest whole number).
Central angle of the sector representing nuclear energy in 2005 = percentage of nuclear energy in 2005 ÷ 100 × 360°
Nuclear energy is approximately 10% (rounded to whole number) in 1995.
Central angle = 

Central angle representing nuclear energy in 2005 = 36°.
The answer for #5 is A, B, and D
8x + 3y = 45 * -2 Negative
2x + 3y = 27 * 8 Positive
-16x - 6y = 90
16x + 24y = 216
24y is equal to 216
y is equal to 216/or 24
y is equal to 9
Which means:
8 + 3y = 216
y = 216/24
y = 9
8x + 3y = 45
8x + 3 (Which is 9) = 45
So the Answer is:
8x=45 - 27
8x= 18
X=18/8
X= 2.25
Hope this helps you
(Good Luck)
80 x 5 = 400
32 x 5 = 160
