Charlie reads quickly. He reads 1\dfrac371 7 3 1, start fraction, 3, divided by, 7, end fraction pages every \dfrac23 3 2 st

OLEGan [10]

<h2>Answer:</h2>

The number of pages he will read in one minute is:

$2\dfrac{1}{7}\ \text{pages}$

<h2>Step-by-step explanation:</h2>

It is given that:

Charlie reads $1\dfrac{3}{7}\ \text{pages}$ in every $\dfrac{2}{3}\ \text{minutes}$ .

We know that:

$1\dfrac{3}{7}=\dfrac{10}{7}$

This means that:

Charlie reads $\dfrac{10}{7}\ \text{pages}$ in every $\dfrac{2}{3}\ \text{minutes}$ .

This means that:

$\text{In}\ \dfrac{2}{3}\ \text{minutes he reads}\ \dfrac{10}{7}\ \text{pages}\\\\\text{Hence}$

$\text{In}\ 1\ \text{minute he will read}\ \dfrac{\dfrac{10}{7}}{\dfrac{2}{3}}\ \text{pages}$

$\text{In}\ 1\ \text{minute he will read}\ \dfrac{10\times 3}{7\times 2}\ \text{pages}$

Hence,

$\text{In}\ 1\ \text{minute he will read}\ \dfrac{15}{7}\ \text{pages}$

Hence,

$\text{In}\ 1\ \text{minute he will read}\ \dfrac{15}{7}\ \text{pages}$

$\text{In}\ 1\ \text{minute he will read}\ 2\dfrac{1}{7}\ \text{pages}$

Explain how the Distributive Property can be used to expand the expression on the left side of the equation. 3(x + 4) = 36.

Tpy6a [65]

Hello!

<em><u>Answer:</u></em>

<em><u>*The answer must have a positive sign.*</u></em>

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, you divide by 3 from both sides of an equation.

$\frac{3(x+4)}{3}=\frac{36}{3}$

And then, you simplify. Then you can also divide by the numbers too.

$36/3=12$

$x+4=12$

Next, you subtract by 4 from both sides of an equation.

$x+4-4=12-4$

And finally, simplify and solve. You subtract by the numbers.

$12-4=8$

Final answer: → $x=8$

Hope this helps!

Thanks!

-Charlie

Have a great day!

Find the circumference of the circle. Use 3.14 for pi

BabaBlast [244]

Answer:

A. C = 43.96

Step-by-step explanation:

Circumference = Diameter * pi

Your diameter in this problem (given by the picture) = 14 inches.

If we plug this into the formula:

C = 14 * 3.14 = 43.96

There is a problem with your question, however, because the length we have found is in inches, while all of your options are in centimeters. However, converting the correct inches answers into centimeters is not an answer choice.
