1. Modeling Real Life Your friend has 3 California postcards, 2 Hawaii postcards, and 4 New York postcards. He gives 1 postcard away, then divides the rest equally among 4 pages of a scrapbook. How many postcards are on each page?

2

Step-by-step explanation:

3+2+4=9

Subtract the one postcard he gave away.

9-1=8

Divide 8 by 4.

8÷4=2

So, there are 2 postcards on each page.

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
