Divide 20m^2n^3 - 10m^2n by 5mn

1 answer:

6 0

$\frac{20 {m}^{2} {n}^{3} - 10 {m}^{2}n }{5mn} \\ = \frac{5mn(4m {n}^{2} - 2m) }{5mn} \\ = 4 {m}^{2} n - 2m \\ = 2m(2mn - 1)$

Hope this helps. - M

The graph shows how many apples Erin can pick if she maintains a constant rate. What is the linear equation for this relationshi

Ainat [17]

Answer:

The linear equation $y=50(x)$ and Erin can pick $50$ apples per hour if she maintains a constant rate.

Step-by-step explanation:

To find the linear equation of the relationship from the graph.

We have to find the coordinates .

Let say $(x,y)=(1,50)$ and $(x_1,y_1)=(2,100)$

Here $x$ variable is the time in hour and $y$ variable is the number of apples.

To find linear equation we have to find the slope (m) of the line by using point-slope form.

$m=\frac{y_1-y}{x_1-x}$

So,

$m=\frac{100-50}{2-1}=50$

The the linear equation will be.

$y=50(x)$

Number of apples Eric pick in an hour is $50$ .

By plugging the value of $x=1$ in the equation we can find the number of apples picked by Erin per hours subsequently $x=2$ for second hour.

In each hour she picks $50$ apples.

Linear equation is $y=50(x)$ and number of apples picked by Eric in an hour is $50$ .

Mrs. Cho has 24 students in her class. Some of her students are also in the play. Explain why it is not possible for exactly 24%

lora16 [44]

Let's start by calculating how many students does 24% represent.
24% * 24 = 0.24 * 24 = 5.76
We got a decimal number as solution. The reason why exactly 24% students can't be in the play is because this percentage does not represent whole number of students. She can't take 0.76 students

If she wanted 25% students to be in a play it would mean she has to take:
25% * 24 = 0.25 *24 = 6 students
