Answer:
The value of given expression for x = - 10 is - 81
Step-by-step explanation:
Given expression as :
3 [tex]\frac{4}{5}[/tex]x - 2 [tex]\frac{1}{2}[/tex]
Or, 3 + [tex]\frac{4}{5}[/tex]x - 2 - [tex]\frac{1}{2}[/tex]
Or, [tex]\frac{19}{5}[/tex]x - [tex]\frac{5}{2}[/tex]
or, [tex]\frac{38 x - 25}{5}[/tex]
Now for x = - 10
[tex]\frac{38\times (- 10) - 25}{5}[/tex]
Or, [tex]{38\times (- 2) - 5}[/tex]
∴ - 76 - 5
Or, - 81
Hence The value of given expression for x = - 10 is - 81 Answer
