6 0

Our expression is below

5(-3.4k-7)+(3k+21) = 0

by solving it for the value of k

(-17k-35)+(3k+21) = 0

-17k+3k-35+21 = 0

-14k-14 = 0

-14k = 14

k = \frac{14}{-14}

k = -1

Oksana_A [137]

Answer:

If the second of the three numbers is  

n

, then the first and third are  

n-  1 and  n + 1 , so we find: 117 = ( n − 1 ) + n + ( n + 1 ) = 3n  

Dividing both ends by  

3  we find: n = 117/  3   = 39

So the three numbers are:

38 , 39 , 40
