a bicycle and a bicycle helmet cost $240 how much did each cost if the bicycle cost 5 times as much as the helmet

$40 and $200

Step-by-step explanation:

Let the helmet's cost be x

Then bicycle costs = 5x

Condition:

=> x+5x = 240

=> 6x = 240

Dividing both sides by 6

=> x = $40

So

Helmet's Cost = x = $40

Bicycle's Cost = 5x = $200

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
