Question

The sum of two Consecutive integers is at least 36. What is the least possible pair of integers?

Answer 1

Answer:

D 18 and 19

Step-by-step explanation:

x =1st integer

x+1 = next consecutive integer

x+ (x+1) >=36

combine like terms

2x+1 >= 36

subtract 1

2x >=35

divide by 2

x >= 17.5

x must be 18

x+1 = 19

Answer 2

Answer:

16 +17 = 33

19 +20 = 39

17 +18 = 35

18 +19 = 37

A and C are less than 36 so they can't be the correct ones.

37 is closer to 36 than 39 is.

The lease possible set is D. 18 and 19
