Answer and Step-by-step explanation:

Assuming that both values of a and b are positive, we get the result to be positive, so a + sign (though you don't have to put that in front of the value).

When you multiply 2 positive values, the result is always positive.

Multiplying a positive and a negative value results in a negative value.

Multiplying 2 negative values together results in a positive value.

Answer:

1636mi/hr

Step-by-step explanation:

2400ft/s = _______mi/hr                   1 hr = 3600s          1mi = 5280ft

2400ft/s   x   3600s/hr   x   1mi/5280ft = 1636mi/hr

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

Answer:

  x = -20

Step-by-step explanation:

First, simplify the equation. Eliminate parentheses and combine terms.

  3(x -1) -8 = 4(1 +x) +5 . . . . . . . given

  3x -3 -8 = 4 +4x +5 . . . . . . . . eliminate parentheses (distributive property)

  3x -11 = 4x +9 . . . . . . . . . . . . combine like terms

We can put all the x-terms on the right by subtracting 3x from both sides.

  3x -11 -3x = 4x +9 -3x

  -11 = x +9

And we can get the x-term by itself by subtracting 9 from both sides.

  -11 -9 = x +9 -9

  -20 = x . . . . . . . . . . this is the solution

__

Check

3(-20 -1) -8 = 4(1 -20) +5

3(-21) -8 = 4(-19) +5

-63 -8 = -76 +5

-71 = -71 . . . . . . . . . true, the answer checks OK

_____

Additional comment

We observe that the two x-terms are 3x and 4x. The smaller of these is 3x, so when we subtract that from 4x we will have a positive result. That is why we chose to subtract 3x, even though it leaves the x-term on the right side of the equation. We could have subtracted 4x to get -x -11 = 9. I find it easier not to make a mistake if the variable has a positive coefficient.

(-7,4] or -7 < X ≥ 4

Step-by-step explanation:

The domain is all applicable X values for the function. In this function, X can be greater than but not including -7, but has to be less than 4 (inclusive).

You can write your answer as (-7,4] or -7 < X ≥ 4.

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.
