C/-7+3.2=2.7
Step 1) Add 7 to both sides because what you do to one side you must do to the other
C/<u>-7</u>+3.2=<u>2.7</u>
<u> +7 +7
</u> C/+3.2=9.7
Step 2) Subtract 3.2 from both side
C/<u>+3.2</u>=<u>9.7
</u> <u> -3.2 -3.2
</u> C/=6.5
Your answer is C=6.5<u>

A postcard is in the shape of a parallelogram. A parallelogram is a quadrilateral with two pair of parallel sides, opposite sides and opposite angles are equal.
Since, the postcard has an area of 12 square inches.
Since, area of parallelogram = 
As area of parallelogram is 12, it means that the product of base and height is 12 square inches.
So, the possible dimensions of postcard are 3 inches and 4 inches and 2 inches and 6 inches.
So, base = 3 inches , height = 4 inches or base = 4 inches , height = 3 inches.
So, base = 2 inches, height = 6 inches or base = 6 inches , height = 2 inches.
0.36363636363 is the answer
