George paid $179.76 for a new lawn mower, after tax, and the tax rate is 7%. What was the original price of the lawn mower?

168

Step-by-step explanation:

Let's make the original price of the lawn as "x"

x + x * 7/100 = 179.76

=> x + 7x / 100 = 179.76

=> 100x/100 + 7x/100 = 179.76

=> 107x = 17976

=> 107x/107 = 17976/107

=> x = 168

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
