Describe how you test the solution set of an equation for its truth value
I will mark brainliest for most understandable answer
help!!

Step-by-step explanation:

Solution Sets for Equations. The set containing all the solutions of an equation is called the solution set for that equation. If an equation has no solutions, we write ∅ for the solution set. ∅ means the null set (or empty set). Equation. Solution Set. 3 x + 5 = 11. { 2 }.

p - 6

step-by-step explanation

so you know that it cost $6 to see a movie you subtract p - 6 to get your answer

hope this !

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
