Answer:

v=9

Step-by-step explanation:

There's a property in geometry called the vertical angles postulate, which means that angles on opposite sides of two intersecting lines are congruent, meaning they have the same measure. So, we already know that one value of the angle is 50 degrees, and 6v-4 is also 50 degrees, because of the vertical angles postulate. We can then solve with basic algebra. 6v-4=50, so 6v=50+4. 6v=54, so v=54/6. 54 divided by 6 is 9, therefore v is equal to 9.

What is the result of the first step when simplifying 13-4(x-5)

Maksim231197 [3]

I don't really get this question but simply put, if you are in college syntax matters very much. (13-4) = 9 *(x-5) = 9x-45.. although in this case. since there isn't a bracket around 13-4. you'd multiply by the -4 first, giving you, 4x-20+30 =4x-10
