What is the value of x?

Step-by-step explanation:

Since they are vertical angles we can write:

2x + 20 = 3(x - 10)

2x + 20 = 3x - 30

x = 50°

50°

Step-by-step explanation:

In the rules of angles, 2x + 20 equals 3(x - 10):

2x + 20 = 3(x - 10)

2x + 20 = 3x - 30                 use the distributive property

2x + 50 = 3x                         add 30 to both sides

= x                                  subtract 2x from both sides

42

step-by-step explanation:

256/6=42

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

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

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
