Find x when y=6 in the literal equation 5x+4y=39

A. 12.6
B. 15
C. 2.25
D. 3

y=6

then,

5x+4y=39---> plug y in to the function

5x+4(6)=39

5x+ 24=39

5x= 39-24

5x= 15

x= 15/5

x= 3

So, the value of x when y=6 in that function is 3 (D)

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

45
