Answer : The value of 'x' that makes Frieda's statement true is, -1
Explanation :
The given expression is:
[tex]1.6(x-4)[/tex]
Frieda states that the value of her expression is -8. That means,
[tex]1.6(x-4)=-8[/tex]
By solving the expression, we get the value of 'x'.
[tex]1.6x-6.4=-8[/tex]
[tex]1.6x=-8+6.4[/tex]
[tex]1.6x=-1.6[/tex]
[tex]x=\frac{-1.6}{1.6}[/tex]
[tex]x=-1[/tex]
Thus, the value of 'x' that makes Frieda's statement true is, -1
