Answer:

C: No solutions.

Step-by-step explanation:

When solving an equation and it provides a false statement, it implies that there are no values that could satisfy the given equation. Simply put, the word "equation" in itself must provide equal values on either sides of the equal sign.

“No solution” means that there is no value, not even 0, which would satisfy the equation.

Therefore, the correct answer is C: No solutions.

need help with error analysis assingment, im in high school and ive always struggled with math alot pls help

Given

A) The angles A and B are supplementary.

If,

$\begin{gathered} \angle A=x+6 \\ \angle B=7x+30 \end{gathered}$

B) The figure,

To find

A) The value of x.

B) The value of x.

Explanation:

A) It is given that,

Angle A and angle B are supplementary.

Then,

$\angle A+\angle B=180\degree$

Hence, the error is in the statement,

Since the angles are supplementary, when added together they equal 90.

As, the correct answer is when added together they equal 180.

That implies,

$\begin{gathered} x+6+7x+30=180 \\ 8x+36=180 \\ 8x=180-36 \\ 8x=144 \\ x=\frac{144}{8} \\ x=18\degree \end{gathered}$

Hence, the value of x is 18 degrees.

B) It is given that,

From, the figure the given angles are interior angles.

Also, the interior angles on the same side of the transversal is supplementary.

Which means when you add them they equal 180.

Hence, the error is in the statement,

Since the angles are adjacent, they are complementary angles.

Which means when you add them they equal 180.

As, the angles are interior angles on the same side of the transversal.

Also,

$\begin{gathered} 64+x=180 \\ x=180-64 \\ x=116\degree \end{gathered}$

Hence, the value of x is 116 degrees.
