Convert the problem to equation or inequality as below.

22

The distance d to school is 1½ miles more than the distance p to

the park.

  • d = p + 1 1/2

23

The perimeter of a square with a side length s is greater than or equal to seventy plus five.

  • p ≥ 70 + 5

or, simplified

  • p ≥ 75

or the perimeter is substituted by side length, p = 4s for the square

  • 4s ≥ 75

24

Kyra's age is at least 3 years more than Al's age.

If Kira's age is k and Al's age is a, then:

  • k ≥ a + 3
