Please help! I will mark you brainliest! Teri incorrectly solved the system of equations below. Identify where the error happened.
2x - 10 y = -30
x - 5y = 20
Step 1:
x - 5y = 20
x = 5y - 20
Step 2:
2(5y + 20) - 10 y = -30
10y + 40 - 10y = -30
40 = -30

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
