Answer:

\Huge \boxed{a=6}

Step-by-step explanation:

a-(7-a)=5

We need to isolate the a variable on one side of the equation to find the value.

Distribute the negative sign.

a-7+a=5

Combine like terms.

2a-7=5

Add 7 to both sides of the equation.

2a=12

Divide both sides of the equation by 2.

a=6

Please be kind and help me with​ this question!<br> WARNING: only if your good at math thank you #3
Alexxx [7]

First of all, look at the figure, The ABC orientation is changed from clockwise to counterclockwise, so an odd number of reflections are involved.

Second, look at the answer choices. Right away, you notice that the last choice (E) involves two reflections. That cannot be the transformation you see. Since that is what the question is asking for, the appropriate choice for the transformation NOT done is ...

... E. reflection across the x-axis followed by a reflection across the y-axis

_____

I have to admit, I went through each of the choices to see if it would work to produce the image you see. All choices except E will do that. All that work turned out to be unnecessary.
