It would be like first round she started with 0 and she loses means points goes negetive
-3 1/2  it is a mixed number solve it==7/2
round 2 she wins 28 1/2    mixed number solved to 57/2
at round  2 her score will be -7/2+57/2=50/2=25

at round 3 she loses again 7/2 means 25-7/2=43/2 will be her score

Her final score should be 21. You can add both 3 1/2 and 3 1/2 which will give you 7. Then substract it from 28.

Law Incorporation [45]

Answer:

B x=2 y=6

Step-by-step explanation:

For ABCD to be parallelogram, following conditions should be satisfied:

2x - 0 = x + 2 & 4y - 8 = y + 10

2x - 0 = x + 2

2x - x = 2

x = 2

4y - 8 = y + 10

4y - y = 10 + 8

3y = 18

y = 18/3

y = 6
