Hat is the value of x in the equation 7x + 2y = 48 , when y = 3?

x = 6

Step-by-step explanation:

When y = 3, we can use this value to substitute into the equation for 'y' in order to solve for 'x':

7x + 2(3) = 48  or 7x + 6 = 48

Subtract '6' from both sides: 7x + 6 - 6 = 48 - 6 or 7x = 42

Divide both sides by '7':  7x/7 = 42/7

Solve for 'x':  x = 6

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

answer: 12

step-by-step explanation:

because yes
