Step-by-step explanation:

I have a few questions about how to get a good friend always to be a good friend always because you are a good friend and you are a good person to work with and you can always make your life easier and more difficult to make your life easier and more difficult to get your life off your hands

Because of the test she did not take, Brandee scored a 9.75% lower average than her average score once her teacher allowed her to take the test again.

The average obtained once Brandee's teacher allowed him to present the missing test is much more accurate regarding Brandee's ability, this can be identified since it went from an average of 85.14% with 7 scores, to one of 84.25% with 8 scores, different from the average of 74.5% obtained thanks to that score of 0.

BRANDEE'S AVERAGE CALCULATION.

In the exercise, you can see Brandee's scores are: 80%, 92%,  91%, 75%, 89%, 84%, 0%, and 85%, if you calculate the average in that case:

But when Ms. Juarez allowed her to make up the missed test, in which she got 78%, The average increased too much:

As can be identified, most of Brandee's scores are above 80%, therefore, it is considered more accurate that her average is above this value, that is, it is an average that would represent much better the ability of Brandee.

  C.  -10

Step-by-step explanation:

Whole numbers are non-negative integers. -10 is not a whole number.

Answer:

1. -29/156 2. 38/45 3. 29/45 4. 113/24 or about 4.7 5. 457/1,  914/2,  1371/3

Step-by-step explanation:

3/13 - 5/12 can be simplified to 36/156 - 65/156. Subtract this and you get -29/156  

4/9 + 2/5 can be simplified to 20/45 + 18/45. Add this and you get

38/45

5/8 - 2/9  can be simplified to 45/72 - 16/72. Subtract this and you get

29/45

3 1/2 + 2 5/12 can be first made irrational to 7/2 + 29/24. This can be simplified to 84/24 + 29/24

113/24 or about 4.7

Not sure about the 457, but to convert it, you multiply it by whatever denominator you have. For example

1x457 = 457/1

2x457 = 914/2

And finally 3x457 = 1371/3
