Paolo is putting a fence around his pool. The length of the pool is 20 feet, the width is (20 minus x) feet, and the area of the pool is 300 square feet. Recall that area is length multiplied by width. The equation below models the area of the pool. 20 (20 minus x) = 300 What is the value of x? Round to the units place. 5 8 15 35

The value of x = 5

Step-by-step explanation:

Length of the pool = 20 feet

Width of the pool = (20 minus x) feet

Area of the pool = 300 square feet

Area of a rectangular pool = length × width

300 = 20 (20 - x)

300 = 400 - 20x

Subtract 400 from both sides

300 - 400 = 400 - 20x - 400

- 100 = - 20x

Divide both sides by -20

x = -100/-20

= 5

x = 5

The value of x = 5

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
