Gracie, Mary, and Nancy cach have a small collection of seashells. Gracie has 5 more than lả times the number of shells Mary has. Nancy has 1 more than 13 times the number of shells Mary has, Gracie and Nancy have the same number of shells. If x is the number of shells Mary has, identify the equation that
represents this situation and identify its solution

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

a sample of water is taken and kept in a beaker in a freezer at a constant temperature of 0°c. if the system is at dynamic equilibrium, which of these statements is true?
