The fourth inherited 8/81 of the estate

Step-by-step explanation:

If I get it correctly:

The first inherited 2/9

The second inherited 19/81

The third inherited 12/27

The fourth inherited x

The estate was divided in 4 parts, so the sum of the 4 parts equal 1

$1 = \frac{2}{9} + \frac{19}{81} + \frac{12}{27} +x \\1 = \frac{2*9}{9*9} + \frac{19}{81} + \frac{12*3}{27*3} +x \\1 = \frac{18}{81} + \frac{19}{81} + \frac{36}{81} +x \\1 = \frac{18+19+36}{81} +x \\1 = \frac{73}{81} +x \\1 - \frac{73}{81} = x \\\frac{81-73}{81} = x \\\frac{8}{81} =x$

Olivia wrapped 6 gifts and prepared 8 giftbags.

Step-by-step explanation:

Write System of Equations:

3x+1.5y= 30 x+y=14

x+y= 14 y=-x+14

3x+1.5y=30

1.5y=3x+30

1.5y divided by 1.5 is y

-3x+30 divided by y is -2x+20

y=-2x+20
