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

lyudmila [28]

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
