1000 gram = 1 kilogram
If 200 gram = $8.12. 1, it means we can get 5 bags of such amount (1000/200 = 5)
Therefore, 1kg = $8.12 * 5 = $40.6
The coefficients in the equation (-x)(3y)(-2x) are the constants -1, 3, and -2.
In order to simplify and determine only one coefficient <span>we should multiply all three constants together to get only one numerical constant .
</span><span>The commutative law</span> says hat you can rearrange a multiplication any way you want. so, (-1)*3*(-2)=(-3)*(-2)=6
The equation can be also simplified written as:
6x^2y
None of the option is the solution.
I believe that the answer is most likely C given it's circumstances, hope this was helpful
