A student evaluated -4+x for x = -9 1/2and got an answer of 5 1/2? What might th student have done wrong.

Sagot :

Answer:

Step-by-step explanation:

Expression evaluated by the student is,

(-4 + x)

For x = [tex]-9\frac{1}{2}[/tex]

Value of the expression will be,

(-4 + x) = [tex]-4+(-9\frac{1}{2})[/tex]

           = [tex]-4-9-\frac{1}{2}[/tex]

           = [tex]-13-\frac{1}{2}[/tex]

           = [tex]-13\frac{1}{2}[/tex]

While student evaluated the value of the expression as [tex]-5\frac{1}{2}[/tex].

Mistake done by the student may be in the first step [tex][-4+(-9\frac{1}{2})][/tex].

He might have subtracted [tex](-9\frac{1}{2})[/tex] from (-4).
