3.5x - 11 = 20.5 what does x equal?
stepan [7]

Answer:

x=9

Step-by-step explanation:

3.5x - 11 = 20.5

3.5x - 11+11 = 20.5+11

3.5x = 31.5

Divide each side by 3.5x

3.5x/3.5 = 31.5/3.5

Use the figure to determine the value of X and y
bogdanovich [222]

Answer:

100,80

Step-by-step explanation:

The opposite angle theorem states that, : "When two lines cross four angles are created and the opposite angles are equal."

y°=80°

Now, check that , x° and y° are in one straight line. A straight line has angle of 180°. So x° and y° should sum up to 180°

x° + y° = 180°

x° + 80° = 180°

x° = 100°
