Chris earns 9.75 per hour but he has to pay 4.15 every day for gas. Which expression shows how much Chris, c, earns in 4 days if he works h hours

c=9.75h−4.15

Step-by-step explanation: c=9.75h−4.15

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
