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.
Answer:
2.4 or 12/5 or 2 2/5
Step-by-step explanation:
To 3 decimal places.
128.59943
Count three places to the right after the decimal point. The third digit is 9, and the fourth is 4. Since the 4th is not up to 5, we leave the 9 that way and so we can not round up the 9 to 10.
So it becomes = 128.599
Thanks.
The graph shown is not a function because points (-1,2) and (-1,0) have the same x value.
