True.
Since
,
and the solutions are decreasing functions.
C. 10/x+8
The easy way to do it would be to take it one step at a time.
Let the number = x
It would be: 9x + 6 = 456
9x = 456 - 6
9x = 450
x = 450 / 9
x = 50
In short, Your Answer would be 50
Hope this helps!
560+ 147= 707
14(40)= 560
14+ 14(1/2)=21
21(7)= 147
