Question

Which equation could be used to solve this problem? The sum of two consecutive integers is 107. Find the integers.
n+1=107
2n+1=107
2n+2=107
n+2=107
Which equation could be used to solve this problem?The sum of two consecutive odd integers is 112. Find the integers
2n + 3 = 112
2n + 2 = 112
2n + 1 = 112
n + 2 = 112

Please Help. I keep failing this test

Answer 1

Bah one question at a time.... I'll help with the first and it should help you with the other 2.

n= the first number in a consecutive pair.
what is a consecutive pair? 2 numbers right next to eachother on the number line.
100 and 101, 8 and 9, etc.
So how do you get the second number? it must be n+1... right?
So now if you add the number and its pair, you have n+n+1=(Whatever your assignment says)
n+n is the same thing as what? n times 2 or 2n

Answer 2

Once you read that, tell me what you think each of the answers is and I'll check for you.
