20 is your value for x

Step-by-step explanation:

Note that these two angles are vertical angles, which means there measurements will be the same. Set the two measurements equal to each other.

3x + 50 = 6x - 10

Isolate the x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS (Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction).

First, subtract 6x and 50 from both sides

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

3x - 6x = -10 - 50

-3x = -60

Next, isolate the x. Divide -3 from both sides

(-3x)/-3 = (-60)/-3

x = -60/-3

x = 20

20 is your value for x.

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
