Answer:

x° is divided into two parts the upper and the lower.

From the above 85° is alternate to the upper part of x°, hence the upper part of x = 85°.

Also 147° and the lower part of x° are co-interior angles, hence the lower part of x = 180° - 147° = 33°

there x° = 85° + 33° = 118°

How to evaluate an algebraic expression?
irinina [24]

"Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, wher all you have to do is simplify; that is more of an order-of-operations kind of question.

Hope this helped                                     BTW can I have brainliest that would help me

Write the matrix equation as a system of linear equations without matrices. [Start 3 By 3 Matrix 1st Row 1st Column 1 2nd Column
ASHA 777 [7]

Answer:

x-2y-4z=8\\5x-4y+7z=5\\-7x+5y+2z=-3

Step-by-step explanation:

Given the matrix equation below:

\left(\begin{array}{ccc}1&-2&-4\\5&-4&7\\-7&5&2\end{array}\right)\left(\begin{array}{ccc}x\\y\\z\end{array}\right) =\left(\begin{array}{ccc}8\\5\\-3\end{array}\right)

We are required to write the matrix equation as a system of linear equations without matrices.

\left(\begin{array}{ccc}1&-2&-4\\&&\\&&\end{array}\right)\left(\begin{array}{ccc}x\\y\\z\end{array}\right) =\left(\begin{array}{ccc}8\\&\\&\end{array}\right)$is equivalent to: x-2y-4z=8

\left(\begin{array}{ccc}\\5&-4&7\\&&\end{array}\right)\left(\begin{array}{ccc}x\\y\\z\end{array}\right) =\left(\begin{array}{ccc}&\\5\\&\end{array}\right)$ is equivalent to: 5x-4y+7z=5

\left(\begin{array}{ccc}&\\&\\-7&5&2\end{array}\right)\left(\begin{array}{ccc}x\\y\\z\end{array}\right) =\left(\begin{array}{ccc}&\\&\\-3\end{array}\right)$ is equivalent to: -7x+5y+2z=-3

Therefore, we have the system of equations:

x-2y-4z=8\\5x-4y+7z=5\\-7x+5y+2z=-3
