X- y = -5 x - y = 1/3 substitution method

x = -5

y = 0

Step-by-step explanation:

x-y = -5 eqn 1

x-y = 1/3 eqn 2

From eqn 1

x-y = -5

x = -5 + y eqn 3

From eqn 1

-5+y-y = -5

y = 0

Eqn 3

x = -5 + 0

x = -5

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
