Solve the system of equations and choose the correct ordered pair.
nasty-shy [4]
The answer is D

Because if you replace the variables just by testing them they give the answer as X=-3 and Y=3.
In which replacing:
3(-3)+5(3)=6
and with the other equation we've got:
4(-3)+2(3)=-6
so they comply with the required to be the correct answer, even though you can make a system of equation.

What are the central angles of the sectors representing nuclear energy in both the years?( you may round the numbers before find
xeze [42]

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 = \frac{6}{100}*360 = \frac{6}{10}*36

= \frac{216}{10} = 21.6

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 = \frac{10}{100}*360 = \frac{1}{1}*36

= \frac{36} = 36

Central angle representing nuclear energy in 2005 = 36°.
