Astudent spends the same amount each week for bus fare in 5 weeks he spends 115 which equation shows his relationship let's= number of weeks

Let c represent the cost of bus fare per week

                 5c = $115

                    c = $25

The student spends $25 per week for bus fare so the rate is $25

The equation to determine the total cost for "x" number of weeks is:

y = $25x

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
