Sam can mow a lawn in 40 minutes. melissa can mow the same lawn in 60 minutes. how long does it take for both sam and melissa to mow the lawn if they are working together? express your answer as a reduced fraction.

24 minutes.

Step-by-step explanation:

We work in rates per minute:

1 / 40 + 1/ 60 = 1/x     where x is the time taken working together.

Multiply through by the LCD 120x:

3x + 2x = 120

x = 120 / 5

x = 24 minutes (answer)

x=half

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
