Ethan rollerbladed a total of 623 \text{ km}623 km over dd days. he rollerbladed the same distance each day. how many kilometers did ethan rollerblade each day?

623/d

Step-by-step explanation:

km

Step-by-step explanation:

Let in one day Ethan rollerbladed x km.

And, According to the question,

In each day he rollerbaded the same distance,

Thus, in d days, he rollerbladed = d × x = dx km

But, Again according to the question,

He rollerbladed a total of 623 km over d days.

⇒ d x = 623 km

⇒ x = 623 / d  km

Thus, He rollerbladed in a day  = km

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
