For each diagram, decide if y is an increase or a decrease relative to x. Then determine the percent increase or decrease.(sry the stuff on the pic is black)

In A: y is a 25% decrease of x

In B: y is a 25% increase of x

Step-by-sep explanation:

For A:

The diagram in A shows that x = 4, while y = 3.

Thus, this means that y decreased by 1, relative to x.

The percentage decease would be:

Therefore, y is a 25% decrease of x.

For B:

The diagram for B shows that x = 4, while y = 5.

Thus, this means that y increased by 1, relative to x.

The percentage increase would be:

Therefore, y is a 25% increase of x.

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510
