anonymous · Answer

I would say that the correct answer choice is D.
A.  49÷ (-7) = -7k ÷ (-7)
      -7=1k 
B. 49∗ (-7) = -7k ÷ (-7)
       -343=1k
C. 49∗  |  - 1 | = -7k ∗ (-7)
             |   -- |
             |   7   |

(49/1)(-1/7) 
  = -49/7 = -7
(-7k)(-7)
 = 49k
 -7=49k
While,
D. D. 49∗  | -1 | = -7k ∗ | -1   |
                 | -- |               | --- |
                 | 7   |               |  7   |

(49/1)(-1/7)
= -49/7= -7
(-7k/1)(-1/7)
=1k
-7=1k
