Answer:
Step-by-step explanation:
8.5*7.5 = 63.75
If you simply solve the equation for w, rather than "guess and check" using the values in the "replacement set," you find ...
... 6w +6 = 60 . . . . simplify the equation
... 6w = 54 . . . . . . . subtract 6
... w = 9 . . . . . . . . . divide by 6
The appropriate choice is ...
... D. 9
It would be: 5x - 8 = 75
5x = 75 + 8
5x = 83
x = 83 / 5
x = 16.6
So, the number & your final answer is 16.6
Hope this helps!
