Kevin has $4.85 in nickels and dimes. If he has 34 fewer dimes than nickels, how many coins (nickels and dimes) does he have altogether?

A. 74 coins

B. 75 coins

C. 76 coins

D. 77 coins

if   x = the number of nickles   and     x-34 = the number of dimes                    then .05x + .10(x-34) = 4.85               or          .15x = 8.25               x = 55

So, nickles = x = 55

dimes = (x-34) = 21

55+ 21 = 76 So, that means your answer is C. 76 coins

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
