Someone help me... please show work​

Answer:

x=5

Step-by-step explanation:

Set the 2 equations equal to each other and solve for x.

11x-28=7x-8

add 28 to both sides (-8+28=20)

11x=7x+20

subtract 7x from both sides (11x-7x=4x)

4x=20

divide both sides by 4 to isolate x (20/4=5)

x=5

O,60 is the same rotation as O,<br><br> -300<br> 120<br> 300
Luba_88 [7]

Answer:

-300

Step-by-step explanation:

A counter-clockwise rotation is positive.

A clockwise rotation is negative.

Start at the top and go counter-clockwise 60 degrees.

Start at the top and go clockwise 300 degrees.

You end up at the same point.

It is -300 because a clockwise rotation is negative.
