Answer:

6

Step-by-step explanation:

We can use the  theorem [ a^2 + b^2 = c^2 ]

8^2 + b^2 = 10^2

b^2 = 36

b = 6

What is the solution to the rational equation x over 2x plus 1 minus 1 over 4 equals 2 over 2x plus 1
aalyn [17]
We want to solve
\frac{x}{2x+1} - \frac{1}{4} = \frac{2}{2x+1}

Subtract 2/(2x+1) from each side.
\frac{x}{2x+1} - \frac{2}{2x+1y} - \frac{1}{4} = 0

Add 1/4 to each side, and simplify the left side.
\frac{x-2}{2x+1} = \frac{1}{4}

Cross multiply.
4(x - 2) = 1(2x + 1)
4x - 8 = 2x + 1

Simplify and solve for x.
4x - 2x = 1 + 8
2x = 9
x = 9/2   or x = 4 1/2.

Answer:  x =  \frac{9}{2} \,\, or \,\, x = 4 \frac{1}{2}

Mt. McKinley, which is the highest elevation in North America, is 20,320 feet above sea level. Death Valley, which is the lowest
Llana [10]

Answer:

<u>20,602 feet</u> is the difference in height between the top of Mt. McKinley and the bottom of the Death Valley.

Step-by-step explanation:

Given:

Mt. McKinley, which is the highest elevation in North America, is 20,320 feet above sea level.

Death Valley, which is the lowest elevation in North America, is 282 feet below sea level.

Now, to find the difference in height between the top of Mt. McKinley and the bottom of the death valley.

<em>Height of Mt. McKinley above sea level = 20,320 feet.</em>

<em>Height of Death Valley below sea level = 282 feet.</em>

Now, to get the difference in height between the top of Mt. McKinley and the bottom of the Death Valley by adding both the heights:

20320+282

=20602\ feet.

Therefore, 20,602 feet is the difference in height between the top of Mt. McKinley and the bottom of the Death Valley.
