The value of a house decreases at a steady rate of 20% each year. What is the total percentage loss (to the nearest integer) in
Westkost [7]

Answer: The total percentage loss would be 67%.

Step-by-step explanation:

Since we have given that

Rate of decline each year = 20%

Number of years = 5

We need to find the total percentage loss in value of the house at the end of 5 years.

So, Total percentage loss would be

1-(1-\dfrac{r}{100})^5\\\\=1-(1-\dfrac{20}{100})^5\\\\=1-(\dfrac{4}{5})^5\\\\=1-(0.8)^5\\\\=0.67\\\\\approx 67%

Hence, the total percentage loss would be 67%.

-6d=-42 can you help me solve please
eduard

Given the equation :

-6d=-42

So, to find d , divide both sides by ( -6 )

So,

\begin{gathered} \frac{-6d}{-6}=\frac{-42}{-6} \\  \\ d=7 \end{gathered}

Note: when we divide two negative numbers, the result will be a positive number
