when $x = 5$, the value of the expression $\frac{20}{-25 + x}-2(x - 10)$ is\n-21\n-9\n9\n19
Answer
Explanation:
Step1: Substitute x = 5 into the fraction
Substitute (x = 5) into (\frac{20}{-25 + x}). (\frac{20}{-25+5}=\frac{20}{-20}=- 1)
Step2: Substitute x = 5 into the second - part
Substitute (x = 5) into (-2(x - 10)). (-2(5 - 10)=-2\times(-5)=10)
Step3: Calculate the value of the whole expression
Add the results of the two - part calculations. (-1+10 = 9)
