I will do questions 2-4 only. I'll leave 1 for you.

2. The width of a rectangle is half the size of its length. the perimeter is 27 feet. what are the dimensions?
27 = 2(x/2) + 2x
27 = x + 2x
27 = 3x
27/3 = x
9 = x
Width = 4.5 feet
Lenth = 9 feet
3. Ivana Tinkles balance on her credit card is $4500. She pays back 1/3 of her balance. How much did she pay back?
4500 x 1/3 = 1500
She paid back $1500
4. What is her new balance?
New balance = $4500 - $1500
New balance = $3000
