Javier designs leather shoes at his workshop. he charges $45 for women's shoes and $50 for men's shoes. he needs to make $2,500 per week to meet his expenses. this situation can be given by 45x + 50y = 2,500, where x is the number of women's shoes and y is the number of men's shoes designed by javier. if he does not have any female customers during a particular week, how many male customers does he need to meet his expenses? (x 0, y 0, x and y take only integer values)

We write the equation that is given above,
                                45x + 50y = 25000
Since there are no women, x should be zero. We are then left with the equation,
                                      50y = 25000
To answer, we divide both sides of the equation by 50 giving us 50. Thus, Javier needs 50 male customers for him to meet his expenses.

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
