Explain why a change from 20 to 40 is a 100% increase, but a change from 40 to 20 is a 50% decrease.
Rainbow [258]

Answer:

Because 20 has to be doubled to become 40. While 40 is twice as much as 20 so you just divide 40 by 20 to get 50%.

Explanation:

20 x 20 = 40 = 100%

40 / 20 = 50%

Soloha48 [4]

Multiplication property of equality

Step-by-step explanation:

We are given that the equation

-\frac{3}{8}x=48

We have to find the property which was applied to solve the equation.

-\frac{3}{8}x=48

Reason: Given

Multiply by -8/3 on both sides

-\frac{8}{3}\times -\frac{3}{8}x=-\frac{8}{3}\times 48

By using multiplication property of equality.

x=\frac{-384}{3}

After simplification

x=-128
