You have a square with an area of 100 meters^2.
if you decrees a pair of opposite sides by 50%. you end up with a rectangle with the area of 50 meters^2.
then you increase the other pair of opposite sides by 50%. you end up with a rectangle with the area of 75 meters^2. OK now I see what I did wrong. 

The correct answer is 75%

Answer:

  -5

Step-by-step explanation:

Substituting x=4 into the equation gives a 2-step linear equation in y. It is solved by isolating the variable and making its coefficient be 1.

__

<h3>use x=4</h3>

When x=4, the equation becomes ...

  -3x +9y = -57

  -3(4) +9y = -57

  -12 +9y = -57

<h3>solve 2-step equation</h3>

The <u>first step</u> is to "isolate" the variable term (9y) by adding the opposite of the constant that is on the same side of the equation. The result is that the variable term is by itself on one side of the equal sign.

  -12 +12 +9y = -57 +12 . . . . . add the opposite of -12

  9y = -45 . . . . . . . . . . . . . . simplify

The <u>second step</u> is to make the coefficient of y be 1. We do that by multiplying by its inverse, 1/9. Equivalently, we divide by 9.

  (1/9)(9y) = (1/9)(-45) . . . . multiply by the inverse of 9

  y = -5 . . . . . . simplify

If x = 7, what is the value of the expression above?
givi [52]

if x= 7 what is the value of x-4

7 - 4

=3

if y=3 what is the value of 8y

8 x 3

= 24

if x=7 what is the value of 3x-4

(3 x 7) - 4

= 17

if x=7 and y=3 what is the value of 2x-7y

(2 x 7) -(7 x 3)

= - 7

if x=7 and y=3 what is the value of 4y-X

(4 x 7) - 3

= 25

Hope this helps
