beks73 [17]
7.5% of 160.

12 / 160 = 0.075

Move decimal 2 places to the left to convert it to a percent, or multiple by 100.

0.075 * 100 = 7.5

 7.5% is your answer.

3(3)^2- 5(4)

Fill in the blank by performing the indicated elementary row operation(s).
Scilla [17]

In this question, we are given a matrix, and we have to perform the given operation.

The matrix is:

\left[\begin{array}{ccc}6&-1&|5\\1&-5&|0\end{array}\right]

The following operation is given:

R_1 \rightarrow -6R_2 + R_1

In which R_1 is the element at the first line and R_2 is the element at the second line.

Updating the first line:

R_{1,1} = -6*1 + 6 = 0

R_{1,2} = -6*-5 - 1 = 30 - 1 = 29

R_{1,3} = -6*0 + 5 = 5

Thus, the filled matrix will be given by:

\left[\begin{array}{ccc}0&29&|5\\1&-5&|0\end{array}\right]
