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
