stepladder [879]

Answer:

B, D

Step-by-step explanation:

Solve all equations:

$x-3x=-2x+4\\ \\-2x=-2x+4\\ \\0=4$

This is false equality, so this equation has no solutions.

$x-\dfrac{1}{3}(3x)=0\\ \\x-x=0\\ \\0=0$

This equality is true for all values of x, so this equation has infinitely many solutions.

$\dfrac{1}{3}x-3=4+2x\\ \\x-9=12+6x\\ \\x-6x=12+9\\ \\-5x=21\\ \\x=-\dfrac{21}{5}$

This equation has the unique solution.

$3x+2-\dfrac{1}{3}(3x)=2+2x\\ \\9x+6-3x=6+6x\\ \\6x+6=6+6x\\ \\0=0$

This equality is true for all values of x, so this equation has infinitely many solutions.

$x-\dfrac{1}{3}x+2=0\\ \\3x-x+6=0\\ \\2x=-6\\ \\x=-3$

This equation has the unique solution.

$\sin 60=\dfrac{\sqrt{3}}{2}$

For

$\cos \theta =\dfrac{\sqrt{3}}{2}$

It indicates $\theta$ lies in I st quadrant. The value of cosine $30^{\circ}$ is equal to $\dfrac{\sqrt{3}}{2}$

Therefore, $\theta$ must be $30^{\circ}$
