Sort of because 500/6 = 83 pages, 100 pages is a reasonable answer.

4525 round to the nearest tenth place

sammy [17]

1. The number 2 is located in the tenths place

2. Since the number 5 is located in the ones place, it's telling 2 to go up (turning 2 into a 3)

Stays the Same: 1,2,3,4
Goes Up: 5,6,7,8, etc...

4,525 ⇒ 4,530

The base of a parallelogram with the area (A) of 72 square inches and height (H) of 6 inches.

Elza [17]

Answer:

Step-by-step explanation:

Let's make a simple equation! It's much, much simpler than you think. Let's look closely.

<h3>Area = Base x Height</h3>

We already know the area, so we can substitute this already.

<h3>72 = Base x Height</h3>

We also know the height, 6.

<h3>72 = Base x 6</h3>

We can now replace "base" as x to make it simpler to solve the equation we made!

<h3>6x = 72</h3><h3>x = 12</h3><h3 /><h2>The base of the parallelogram is 12 inches.</h2>

Ahmed is solving the following equation for xxx.

Dennis_Churaev [7]

Answer:

No

Step-by-step explanation:

An extraneous solution is a root of a transformed equation which is not a root of the original equation because it was not included in the domain of the original equation.

Ahmed is solving $2\sqrt[3]{x-7}+11=3$ for x.

His steps were:

$\begin{aligned}2\sqrt[3]{x-7}&=-8\\ \sqrt[3]{x-7}&=-4\\ \left(\sqrt[3]{x-7}\right)^3&=(-4)^3\\ x-7&=-64 \end{aligned}$

Since cube roots <u>do not give two solutions when solved</u>, it is <u>not necessary </u>to check his answers for extraneous solutions.
