When y=7.5 x=2 what is the value of y when x is 2 1/4
swat32
<h2>Answer:</h2>

The value of y is 8.4375

<h2>Step-by-step explanation:</h2><h3>Known :</h3>
  • y = 7.5
  • x = 2

<h3>Asked :</h3>
  • The value of y when x is 2.25

<h3>Solution :</h3>

2/7.5 = 2.25/y

Do a cross multiplication,

2/7.5 = 2.25/y

=> 20/75 = 2.25/y

=> 75 . 2.25 = 20y

=> 168.75 = 20y

Reverse the equation,

168.75 = 20y

=> 20y = 168.75

Find the value of y,

20y = 168.75

=> y = 8.4375

<h3>Conclusion :</h3>

y = 8.4375

The perimeter of the rectangle is 76 units. Find the length of side pq
larisa [96]

Answer:   PQ=16\ units

Step-by-step explanation:

The missing figure is attached.

The perimeter of a rectangle is:

P=2l+2w

Where "l" is the lenght and "w" is the width.

You can identify in the figure that:

w=SR=PQ=2z+2\\\\l=QR=PS=3z+1

Then, knowing the perimeter of the rectangle, you can make the subsitution into the formula:

 76=2(3z+1)+2(2z+2)

Now you must simplify and solve for "z"

76=6z+2+4z+4\\\\76-6=10z\\\\70=10z\\\\\frac{70}{10}=z\\\\z=7

Finally, substituting the value of "z" into  PQ=2z+2, you get:

 PQ=2(7)+2=16\ units
