Question

Model the situation.

The sum of two consecutive integers is 85. Find the integers that satisfy this condition.
Answer choices

A) 1 + 2 = 85

B) x+(x+1)=85

C) x+x=85

D) x+2x=85

Answer 1

Option B is correct

Explanation:

Let the number be x

Second number = x + 1

Sum = 85

x + x + 1 = 85

2x + 1 = 85

2x = 85 - 1

2x = 84

x = 84/2 = 42

Numbers are 42 and 43

Answer 2

B) x+(x+1)=85

Explanation:

Consecutive means in a row

Let x be the first integer

x+1 is the next integer

x+x+1 = 85
