Need with problem 40,41 and 42! 15 points

40) w = 32/3

41) x = 23/4

42) w = 1/12

Step-by-step explanation:

40) Real world problem:

If Lisa takes of the pie from a total of slices, then the remaining pie is . Find w.

So, the equation would become:

This can be written as:

This is equivalent to

Since, the denominator is the same, the numerators can be added now.

Hence, the answer is 32/3.

41) The given equation is:

and

So,

The answer is 23/4.

42) The given equation is

The answer is 1/12.

20

step-by-step explanation:

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
