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]

Answer: 3

Step-by-step explanation:

At first you would subtract 39 from 60. Then you would do 21/5.5 and you would get 3.818… and due to the fact you can't go over 60 you would round to 3 and not 4

Can someone help me with this

Let's solve this problem step-by-step.

STEP-BY-STEP EXPLANATION:

We will be using simultaneous equations to solve this problem.

The sum of angles on a straight line is 180°.

( R ) and ( 2x + 5 ) are both on the same straight line.

Therefore:

Equation No. 1 -

R + 2x + 5 = 180

R = 180 - 2x - 5

R = 175 - 2x

Vertically opposite angles are equivalent to each other.

( R ) is vertically opposite ( 3x + 15 ).

Therefore:

Equation No. 2 -

R = 3x + 15

Substitute the value of ( R ) from the first equation into the second equation to solve for ( x )

R = 3x + 15

175 - 2x = 3x + 15

- 2x - 3x = 15 - 175

- 5x = - 160

x = - 160 / - 5

x = 160 / 5

x = 32

Next we will substitute the value of ( x ) from the second equation into the first equation to solve for ( R ).

Equation No. 2 -

R = 175 - 2x

R = 175 - 2 ( 32 )

R = 175 - 64

R = 111

FINAL ANSWER:

Therefore, the answer is:

R = 111

x = 32

Hope this helps! :)
