Answer:

8/21

Step-by-step explanation:

Add up the fraction that is not shaded

2/7 + 1/3

Get a common denominator of 21

2/7 *3/3 + 1/3 *7/7

6/21 + 7/21

13/21

The entire circle is 21/21

Subtract the unshaded from the entire circle to get the shaded

21/21 -13/21

8/21

The length of each side of a square was decreased by 2 inches so the perimeter is now 49 inches. What was the original length of

aleksley [76]

The Original length of each side of square was 14.25 inches.

Step-by-step explanation:

Perimeter of a square is given by:

Perimeter = 4 * side

Let x be the original length of each side of square

decreasing 2 inch will mean

$x-2$

Perimeter of square after reducing 2 inches from each side

$4(x-2) = 49\\4x-8 = 49\\4x = 49+8\\4x = 57\\\frac{4x}{4} = \frac{57}{4}\\x = 14.25$

So,

The Original length of each side of square was 14.25 inches.
