Answer:
The value of given expression \(\frac{20}{-25+x}-2(x-10)\) at x = 5 is 9.
Step-by-step explanation:
Given expression \(\frac{20}{-25+x}-2(x-10)\)
We have to find the value given expression at x = 5.
Consider the given expression \(\frac{20}{-25+x}-2(x-10)\)
To find the value at x= 5 , put x = 5 in expression , we have,
\(\Rightarrow \frac{20}{-25+5}-2(5-10)\)
Solving , we get,
\(\Rightarrow \frac{20}{-20}-2(-5)\)
Simplify, we get,
\(\Rightarrow -1+10\)
\(\Rightarrow 9\)
Thus, the value of given expression \(\frac{20}{-25+x}-2(x-10)\) at x = 5 is 9.
