Sierra walks her dog Pepper twice a day. Her evening walk is two and a half times as far as her morning walk. At the end of the week, she tells her mom, “I walked pepper for 30 miles this week! How long is her morning walk?

(30*2)/49

Step-by-step explanation:

let her morning walk distance be x

her evening distance walk =2 1/2 x

= 5x/2

her daily walk distance =5x/2+x

= 5x/2+2x/2=7x/2

her weekly walk distace= 7x/2*7=49x/2=30miles

x= (30*2)/49

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
