Chris bought six pounds of apples for 10.80. How much would 15 pounds of apples cost at the same price per pound?

$27

Step-by-step explanation:

10.80/6=1.8

1.8×15= 27

the cost is $1.80 per pound

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
