Step-by-step explanation:
Given
-30 = - 0.4 k
30 = 0.4k
k = 30 / 0.4
k = 75
hope it helps :)
100%/x%=75/15
<span>(100/x)*x=(75/15)*x - </span>we multiply both sides of the equation by x
<span>100=5*x - </span>we divide both sides of the equation by (5) to get x
<span>100/5=x </span>
<span>20=x </span>
<span>x=20</span>
