The local bike shop sells a bike and accessories package for $225. if the bike is worth 8 times more than the accessories, how much does the bike cost?

$200

Step-by-step explanation:

let x be the cost of accessories

let 8x be the cost of the bike

8x+x = 225

9x = 225

x = 225/9

x = 25

8x = $200

Step-by-step explanation:

1)

Bike's worth: 8a (where a=accessories)

Accessory: a

So...

8a+a=225

9a=225

a=25

So the accessory costs $25 dollars!

2)

bike + accessory=$225

We already know that the accessory costs $25.00! So we can just replace the accessory in the equation above with 25.

bike+25=225

bike= $200

a rhombus is a parallelogram enjoying his symmetry.

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
