One number is four more than a second number. two times the first number is 10 more than four times the second number

Write an equation for each statement:

:

"one number is four more than a second number."

x = y + 4

:

" two times the first number is four more than four times the second number"

2x = 4y + 4

;

From the 1st equation, substitute (y+4) for x in the above equation

2(y + 4) = 4y + 4

2y + 8 = 4y + 4

8 - 4 = 4y - 2y

4 = 2y

y = 4%2F2

y = 2, the second number

and

x = 2 + 4

x = 6, a number

Step-by-step explanation:

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

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
