Respuesta :

inverse variation

k=yx

k = 5(2.5)

k =12.5


12.5 = yx

12.5 = y (20)

divide by 20

12.5/20 =y

.625 =y

Choice B

ANSWER:

FIRST STEP:

k = 5(2.5)   (5(2.5) means 5 x 2.5)

k =12.5

SECOND STEP

12.5 = yx

12.5 = y(20)

12.5/20 =y     (ur going to divide them cuz u switched places multiplication becomes division and when u have + it becomes - and the other way round)

0.625 =y

so ur answer is B
