Explain why a change from 20 to 40 is a 100% increase, but a change from 40 to 20 is a 50% decrease.Increasing 20 to 40 is the same as increasing 20 by c. So, it is a 100% increase. Decreasing 40 to 20 is the same as decreasing 40 by one-half of c. So, it is a 50% decrease.
I don't understand how to fill in the blanks.

Answers

I believe the answer you are looking for is:

Increasing 20 to 40 is the same as increasing 20 by 20 (or itself), so it is a 100% increase. Decreasing 40 to 20 is the same as decreasing 40 by 1/2 or by 20. So it is a 50% increase.

Basically, when going from 20 to 40, the number is being doubled, and when youre going from 40 to 20 you are cutting the number in half.

Answer:

The first blank is 20 and the second is actually 40

Can someone help me out!!!??? Please

Answers

Answer:

see below

Step-by-step explanation:

The two marked points are equidistant from their average, which is ...

(-3 +9)/2 = 6/2 = 3

The distance they are from that average is 9-3 = 3 -(-3) = 6.

So, you want an expression that is equivalent to ...

|x -3| = 6

Subtracting 1 from both sides of this equation gives you the one seen in choice B:

|x -3| -1 = 5
