3x+ 50=6x- 10
Subtract 3x on both sides
3x+50=6x-10
-3x -3x
You get
50=3x-10
Add 10 on both sides
50=3x-10
+10 +10
You get
60=3x
Divide both sides by 3
X=20

Answer:

x = 20

Step-by-step explanation:

The two indicated angles are vertical angles and vertical angles are equal

3x+50 = 6x-10

Subtract 3x from each side

3x-3x+50 = 6x-10-3x

50 = 3x-10

Add 10 to each side

50+10 = 3x-10+10

60 = 3x

Divide each side by 3

60/3 = 3x/3

20 =x

2. Distributive Property

4 is distributed and multiplied inside the parenthesis to x and -5.


4. Subtraction Property of Equality

x is subtracted from both sides of the equation.

4x - x - 22 = x - x + 3

3x - 22 = 3


5. Subtraction Property of Equality

22 is added to both sides of the equation.

3x - 22 + 22 = 3 + 22

3x = 25


6. Division Property of Equality

3 is divided from both sides of the equation.

\frac{3x}{3} = \frac{25}{3}

x = \frac{25}{3}

In Triangle A B C, what is the value of x? Triangle A B C. Angle A is (10 x minus 10) degrees, angle B is (8 x) degrees, angle C
svp [43]

Answer:

6.5

Step-by-step explanation:

The sum of all angles in a triangle are 180 degrees.

=> 10x -10 + 8x + 10x + 8 = 180

=> 28x -2 = 180

=> 28x = 182

=> x = 6.5

So, Angle A = 10 x 6.5 -10 = 65 - 10 = 55 degrees

     Angle B = 8 x 6.5 = 52 degrees

     Angle C = 10 x 6.5 + 8 = 65 + 8 = 73 degrees.

55 + 52 + 73 = 55 + 125 = 180 degrees
