4. The sum of two consecutive odd integers is at least 80. Write an inequality to represent the problem

Answer 1

Let x = larger odd integer

then (x-2) is the smaller odd integer

Translate:

"sum of two consecutive odd integers is 80" means (x-2) + x = 80

2x -2 - 80

2x = 82

x = 41

Answer 2

Answer: x ≥ 39

Explanation:

Let x represent the 1st odd integer

Then x + 2 represents the 2nd odd integer

1st odd # plus 2nd odd # is at least the Sum

x + x + 2 ≥ 80

x + x + 2 ≥ 80

2x + 2 ≥ 80

2(x + 1) ≥ 2(40)

x + 1 ≥ 40

x ≥ 39
