Kenneth bought x adult tickets at $10 each and y children tickets at $5 each. He spent $120 total. Write an equation to represent this situation.
Then, solve for y.

10x+5y=120

y=-2x+24

Step-by-step explanation:

x=adult tickets

y=children tickets

120=total spent

10x+5y=120

5y=120-10x

y=(120/5)-(10x/5)

y=24-2x or y=-2x+24

1/5x+9 2/5y+7

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
