The pool at your campsite measures 8 meters by 20 meters. it is surrounded by a path of uniform width, as shown in the figure. the area of the pool and the path combined is 540 square meters. write and solve an equation to fund the width of the path.

5 m

Step-by-step explanation:

The area of rectangle is given by:

A = Length × Breadth

Given, the length of pool + path = 20 +2x

Breadth of the pool + path = 8+2x

Area of pool and the path = 540 m²

⇒

⇒

The length cannot be negative. Therefore, the width of the path is 5 m.

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
