Here's how to find out:
Take the equation: d/0.2 = 3d + 2.1
Multiply each side by 0.2 : d = 0.6d + 0.42
Subtract 0.6d from each side: 0.4d = 0.42
Divide each side by 0.4 : d = 1.05
________________________________
This answer has been changed.
I got d = -0.75 the first time.
Then I came back and changed it.
It's correct now. d = 1.05
Answer:
we approach the issue by taking note of that a 2 x 2 matrix can either have 1 0r 2 pivot columns. If the matrix has no pivot columns then every entry in the matrix must be zero.
-> if our matrix has two pivot columns then : ![\left(\begin{array}{rr}-&*&0&-\end{array}\right)](https://tex.z-dn.net/?f=%5Cleft%28%5Cbegin%7Barray%7D%7Brr%7D-%26%2A%260%26-%5Cend%7Barray%7D%5Cright%29)
-> if our matrix has one pivot column then we have a choice to make. If the first column is pivot column then: ![\left(\begin{array}{rr}-&*&0&0\end{array}\right)](https://tex.z-dn.net/?f=%5Cleft%28%5Cbegin%7Barray%7D%7Brr%7D-%26%2A%260%260%5Cend%7Barray%7D%5Cright%29)
->otherwise, if the pivot column is the second column then: ![\left(\begin{array}{rr}0&-&0&0\end{array}\right)](https://tex.z-dn.net/?f=%5Cleft%28%5Cbegin%7Barray%7D%7Brr%7D0%26-%260%260%5Cend%7Barray%7D%5Cright%29)

a. 180 b. 18 c. 54 d. 30
*Check the attachment for the pie chart
Answer:
C. 54
Step-by-step explanation:
Total number of students under survey = 300
Percentage of students who chose fish as their favorite = 18%
Number of students who chose fish as their favorite pet = ![\frac{18}{100} * 300](https://tex.z-dn.net/?f=%20%5Cfrac%7B18%7D%7B100%7D%20%2A%20300%20)
![= 18 * 3](https://tex.z-dn.net/?f=%20%3D%2018%20%2A%203%20)
54 students chose fish as their favorite pet.
