Looking at the choices, I say all of them are incorrect. But the closest answer would be the second one, but only if a typo error is corrected. Let's investigate each choice.

The equation 10÷15=10⋅5 is true because multiplication and division are inverse operations.
Multiplication and division are inverse operations, but the application done here is incorrect. The correct application should be: 10/15 is 2/3. Now if you multiple 2.3 to 15, the answer is 10. The inverse relationship is not an equality. 10/15 is 2/3 and 10×5 is 50. Clearly, they're not equal.

The equation 10÷15=15⋅10 is true because of the commutative property of multiplication.
I think this is the answer if it were 10×15 = 15×10. That is a proper application of the commutative property of multiplication, which states that the order does not matter when multiplying numbers.

The equation 10÷15=15÷10 is true because of the commutative property of division.
There is no such thing as commutative property of division. If it were, there will be no proper fractions.

The equation 10÷15=110⋅15 is true because of inverse division operations.
110×15 is 1650 while 10/15 = 0.6667. These are not equal.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)

= sin(7pi/6 - 2pi/6)

= sin(5pi/6)

= sin(pi - pi/6)

= sin(pi/6)

= 1/2

sin 7pi/6 - sin pi/3

= sin (pi + pi/6) - sin pi/3

= -sin pi/6 - sin pi/3

= -1/2 - sqrt(3)/2

= -(1+sqrt(3))2
