anzhelika [568]

Answer:

x = (-12/7 , 0)

y= (0,4)

Y = 4        and X = 0

Elenna [48]

Answer:

The answer here would be 1/6.

Step-by-step explanation:

If Amelia originally has 12 marbles (12/12), then gives away 2, she then has 10 marbles (10/12). This means she gave away 2 of the 12 marbles she has (2/12). This fraction can then be reduced to 1/6 by dividing the denominator and numerator by 2.
