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°
You must distribute first.
8 times (3x-2)= 24x-16
2 times (12x-5.5)= 24x-11
What you have left is
(24x-16)-(24x-11)
24x-24x=0
-16- -11=-5
The answer is -5
What its this you are working on
I was taught to get a common denominator and then arrange them in the correct order.
So first you find out what all the denominations can be multiplied to. That would be 40
So you multiply the bottom of each fraction by a number that will get 40.
3/4 * 10 = 30/40
7/8 * 5 = 35/40
3/5 * 8 = 24/40
Then you get 30/40, 35/40, and 24/40.
Then you organize the m.
24/40, 30/40, and 35/40
