You plug the x and y values back into both equations. If both come out to be true statements ie. 4=4, 7=7 your answer is correct. If one or both of the equations turn into false statements, the ordered pair is not the solution to the system.

Answer:

56°

Step-by-step explanation:

hii!

to solve this, we need to know that the angles of a triangle all add up to 180 degrees.

we are going to make an x equation here.

2x+3x+40=180

5x+40=180

    -40  -40

5x=140

/5   /5

x=28

angle a is 2x, so the answer would be 28*2 which is 56°

hope this helped out :)

-104=-8(k+8) <br><br> K = ?<br> Solution please if can?
maksim [4K]

Let's solve this question by step by step.

Layout equation.

−104=−8(k+8)

Step 1: Simplify both sides of the equation.

−104=−8(k+8)

−104=(−8)(k)+(−8)(8)(Distribute)

−104=−8k+−64

−104=−8k−64

Step 2: Flip the equation.

−8k−64=−104

Step 3: Add 64 to both sides.

−8k−64+64=−104+64

−8k=−40

Step 4: Divide both sides by -8.

-8k/-8=-40/-8

The answer for this problem is k=5.
