Hence, option C is true.
Step-by-step explanation:
Given the expression

Solving for 'm'

Flip the equation

Expanding by applying the distributive law: 

Add (-1)/2 × kn to both sides

simplify

Divide both sides by k/2


Therefore,

Hence, option C is true.
Answer:
0.5
Step-by-step explanation:
0.42 x = 0.21
x=0.5
So think of it like this she starts off $32 negative and subtract 3 from each box of cards she makes . So each box of cards she will make $8 that being said
32/8 =4 (it will take 4 box of cards to pay off her booth expense).
Sales would be 11x 4 =44
Expenditures would be 3x4 =32 (the amount used to make cards ) +32(the amount paid for the booth)
Which in total would be $64
D.) because it's proportional. Y=x/2
