Answer:

The answer is -20.

Step-by-step explanation:

(8 × 5) - (-6 × -10)

= 40 - 60

= -20

So first we can find -6 times -10. Since there are two negatives, the answer will be positive. -6 times -10 =60. Then we need to find 8 times 5. 8 times 5 is 40.
Now we have 40-60=-20.
The answer is -20

27% of the students in a school are in grade 6. This is 540 students. How many students are in the school?
Anettt [7]

There are a total of 2,000 students in the school.

1.) There are 540 students in the 6th grade. 540 is only 27% of students compared to the total. To find the total students in the whole school, we divide 540 by 27%.

2.) We first change 27% into a decimal by moving the point two times to the left. (Rule to change the percent into a decimal)

27% = .27

3.) Before we divide, we remove the decimal by moving the decimal two times to the right and so do we to 540.

.27 = 27

540. = 54000.

4.) Now we have 54000 divided by 27 which give us the answer of 2,000.

Hope this Helps!!!

When using the rational root theorem, which of the following is a possible root of the polynomial function below? f(x)=2x^2-4x+9
Norma-Jean [14]

The only option that meets the root theorem is option b.

<h3>which of the following is a possible root of the polynomial function below?</h3>

The polynomial function is:

f(x) = 2x^2 - 4x + 9

The rational root theorem says that if a root is a rational number, then the leading coefficient must be divisible by the denominator of the rational number and the constant term must be divisible by the numerator.

In this case, the constant is 9, and the only option such that the constant is divisible by the numerator is option b: 3

Where 3 is a rational number:

3 = 3/1

The numerator is 3 (which divides 9) and the denominator is 1 (which divides the leading coefficient 9. (notice that it meets the theorem, but it is not an actual root).
