Answer:
x = 20
Step-by-step explanation:
The angles that are marked are called "vertical angles" (I think of a pair of scissors) The two angles are equal to each other. (They get bigger or smaller together, like a pair of scissors)
So, set them equal to each other and solve.
3x + 50 = 6x - 10
SUBTRACT 3x from both sides.
50 = 3x - 10
ADD 10 to both sides.
60 = 3x
DIVIDE both sides by 3.
20 = x
First collect the like terms together= -228+-189+384
then work out=-228+-189+384
=-417+384
=-33
the answer is -33
hope i helped
Answer:
x= 20 x =-5
Step-by-step explanation:
x^2 – 15x – 100 = 0.
What two numbers multiply to -100 and add to -15
-20 * 5 = -100
-20 +5 = -15
(x-20) (x+5) =0
Using the zero product property
x-20 =0 x+5 = 0
x= 20 x =-5
