Sally and her dad live in Fort Worth. Herdad is five times her age. Their combined

age is 50. How old is her dad?_______________

x = Sally’s age

5 x = dad’s age

x + 5 x = 506 x = 50

x = 50 / 6 = 25 / 3 = 8 1 / 3

years

dad’s age = 5 (8 1 / 3 ) = 40 1 / 3 years

In Jacksonville, the perimeter of arectangular park is 1 mile (5280 feet).the length is 240 feet more than threetimes the width. Find the length of the

park.

_______________

x = width3 x + 240 = length2 l + 2 w = perimeter2(3 x + 240) + 2 x = 52806 x + 480 + 2 x = 5280

8 x + 480 = 52808 x = 4800x = 600

3 (600) + 240 = length = 1800 + 240 = 2040
