Step-by-step explanation:

Well Well, so from Lesson 4 to 6 The $ added is 55 then from lesson 6 to 9 the $ added is 82.50. So you subtract 82.50-55=$27.50 which is the cost per lesson. Then to find out the initial fee you do 4*27.50=110 which means that you subtract 145-110=$35 and you get the initial fee. What you do to get the the initial fee is you go back to 0 lessons that's why I multiplied 4*27.50 and subtract that from the cost 145 and u get the initial fee! Hope this helped you comprehend what they're asking you!

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
