Question

the sum of two rational numbers is -8. if one of them is -17/9, then the other is​

Answer 1

Answer:

other number is (- 55 / 9)  or  - 6.11

Step-by-step explanation:

X + Y = - 8

let X = - 17 / 9       as one them is -17/9

-17/9 + Y = - 8

Y = - 8 + (17 / 9)

Now do LCM

Y = (((- 8 * 9) + 17) / 9)

Y = ((- 72 + 17) / 9)

Y = (- 55 / 9)

    (OR)

Y = - 6.11

Answer 2

Answer:

other number is (- 55 / 9)  or  - 6.11    

Step-by-step explanation:

X + Y = - 8  

let X = - 17 / 9       as one them is -17/9  

-17/9 + Y = - 8  

Y = - 8 + (17 / 9)  

Now do LCM  

Y = (((- 8 * 9) + 17) / 9)  

Y = ((- 72 + 17) / 9)  

Y = (- 55 / 9)  

   (OR)  

Y = - 6.11
