The sum of two consecutive numbers is n+1. What are the numbers?

olga55 [171]

Number A: n

Number B: (n-1)

---------------------------

Let's search for the value of (n) to find the number A and B...

$n+\left( n-1 \right) =n+1\\ \\ n+n-1=n+1\\ \\ 2n-1=n+1\\ \\ 2n-n=2\\ \\ n=2$

If n=2,

Number A = 2

Number B = 1

The two consecutive numbers are 1 and 2.

suzi starts her hike at a elevation if -225 below sea level. When she reaches the end of the hike, she is still nelow sea level

sp2606 [1]

The change is elevation is 98 feet.

There are a couple different ways to get this answer. You could:
A. Subtract 127 from (positive) 225, to get the height difference. Or...
B. Subtract the starting height from the ending height (-127 - (-225)) which would also give you the height difference.

I hope this helps!
