ownership has decreased by 0.025 million households per year, and cat ownership has increased by
0.375 million households per year. how many years, y, will it take for them to be equal?

can someone answer this question plz

step-by-step explanation:

pls ask

4x and 6y

im not sure though

hope it you

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
