Answer:

x=-52/29

Step-by-step explanation:

-3(42x+46)=-15(-22-9x)

-126x-138=330+135x

-126x-135x-138=330

-261x-138=330

-261x=330+138

-261x=468

x=468/-261

x=-52/29

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%
