1. Answer is 14.
you first do 8x6 cause of BEDMAS, which is 48. then subtract 12, which gives you 36. then subtract 36 from 50 because 50 is the total amount it should be on both sides.
50 - 36 = 14
2. Answer is 8
5x3 is 15, + 2 is 17. then 20 - 17 gives you 3. you then have 24 divided by a number, and that number is 8 because 24 divided by 8 gives you three
Using weighed averages, it is found that:
- The final grade is 91.
- The final grade is 66.8.
- The higher grade would be 79.55, with the second grading scheme.
- On average, she sold $48,280 per day.
- On average, she makes $12.5 per hour.
---------------------------------------
To find the weighed average, we multiply each value by it's weight.
---------------------------------------
Question 1:
- Grade of 91, with a weight of 67%.
- Grade of 91, with a weight of 33%.
Thus:

The final grade is 91.
---------------------------------------
Question 2:
- Grade of 83, with a weight of 40%(highest grade).
- Grade of 60, with a weight of 30%.
- Grade of 52, with a weight of 30%.
Thus:

The final grade is 66.8.
---------------------------------------
Question 3:
With teacher 1:
- 75 with a weight of 25%.
- 80 with a weight of 10%.
- 85 with a weight of 40%.
- 62 with a grade of 25%.
Thus:

---------------------------------------
With teacher 2:
- 75 with a weight of 15%.
- 80 with a weight of 10%.
- 85 with a weight of 60%.
- 62 with a weight of 15%.
Thus:

The higher grade would be 79.55, with the second grading scheme.
---------------------------------------
Question 4:
- Average of $36,432, with a weight of

- Average of $51,834, with a weight of

Thus:

On average, she sold $48,280 per day.
---------------------------------------
Question 5:
- Average of $14.84, with a weight of

- Average of $10.76, with a weight of

Thus:

On average, she makes $12.5 per hour.

When the point is on the x axis, then the y coordinate=0
when the pointis on the y axis then the x coordinate=0 as well
So each track practice =3 miles
6miles/3miles= 2
Which gives you an answer of 2 track practices.
