20=
20=
\,\,-10r
−10r

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    -10*r-20-(-20)=0

Step by step solution :

Solving a Single Variable Equation:

1.1      Solve  :    -10r = 0

Multiply both sides of the equation by (-1) :  10r = 0

Divide both sides of the equation by 10:

                    r = 0

One solution was found :

r = 0

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

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
