Suppose y varies directly with x and inversely with z. If y = 14 when x = 7 and z = 3, what is x when y = 3
and z = 8? Use the step-by-step process you learned to solve this problem.
Step 1: Set up the correct type of variation equation,
y = kxzy
COMPLETE
Step 2: Determine the constant of variation.
DONE

d. is the correct answer

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
