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