Question

Evaluate the expression 3 4/5x-2 1/2 for x =-10

Answer 1

Answer:

The value of given expression for x = - 10  is - 81

Step-by-step explanation:

Given expression as :

3 $\frac{4}{5}$x - 2 $\frac{1}{2}$

Or, 3 +  $\frac{4}{5}$x  - 2 -  $\frac{1}{2}$

Or,  $\frac{19}{5}$x -  $\frac{5}{2}$

or,  $\frac{38 x - 25}{5}$

Now for  x = - 10

$\frac{38\times (- 10) - 25}{5}$

Or, ${38\times (- 2) - 5}$

∴ - 76 - 5

Or, - 81

Hence The value of given expression for x = - 10  is - 81  Answer
