two and a half hours a day.

write an equation where x is

the number of days and y is

the total number of hours.

what is the constant of

proportionality? in the problem above how many hours will bruno have listens after 12 days this is last three questions i need with will mark brainiest you so much these are 2 question the top is the first second is the bottom

-9

step-by-step explanation:

d

step-by-step explanation:

the constant of proportionality is 2.5

the number of hours that

Bruno would have listened after 12 days is 30

Step-by-step explanation:

Let x represent the number of days.

Let y represent the total number of hours.

Bruno listens to podcasts for

two and a half hours a day.

Let k represent the constant of

proportionality. It means that

k = y/x = 2.5/1

k = 2.5

The expression becomes

y = 2.5x

Therefore, the number of hours that

Bruno would have listened after 12 days would be

y = 12 × 2.5 = 30 hours

the constant of proportionality is 2.5

the number of hours that

Bruno would have listened after 12 days is 30

Step-by-step explanation:

Let x represent the number of days.

Let y represent the total number of hours.

Bruno listens to podcasts for

two and a half hours a day.

Let k represent the constant of

proportionality. It means that

k = y/x = 2.5/1

k = 2.5

The expression becomes

y = 2.5x

Therefore, the number of hours that

Bruno would have listened after 12 days would be

y = 12 × 2.5 = 30 hours
