Step-by-step explanation:
5x + 3y = 6
5(3) + 3(-3) = 6

therefore point lies on the line
Answer:
x =21
Step-by-step explanation:
So we know that:
And that the two angles are vertical angles.
Since they are vertical angles, their measurements are equivalent. Thus, to find x, set the equations equal to each other:
Now, solve for x. Add 30 to both sides. The left side cancels:
Now, subtract 2x from both sides. The right cancels:
Thus, the value of x is 21.
I think it is B but im honestly unsure.
