The formula for the perimeter of a rectangle is P = 2ℓ + 2w, where ℓ is the length and w is the width. The perimeter of a flower garden is 54 feet. Its length is 6 feet more than twice its width. Let the width of the garden be represented by w. Which equation below can be used to describe this situation?

P= 12+4w

Step-by-step explanation:

Given: The formula for the perimeter of a rectangle is P = 2ℓ + 2w, where ℓ is the length and w is the width.

let w = width of rectangle.

then, length = 6+w

Put this in place of ℓ, we get

Perimeter : P= 2 (6+w)+2w

⇒P= 12+2w+2w

⇒ P= 12+4w

hence, the equation can be used to describe this situation : P= 12+4w

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
