I am better at substitution, but you want to get the equations as similar as possible, but are the opposite, so you can cancel it out.

Solve your equation using trail and improvement. A number plus ten times its square root is is equal to one thousand

Alex

Answer:

$x \approx 729$

Step-by-step explanation:

Given

Let the number be x

So:

$x + 10\sqrt x = 1000$

Required

Using trial and improvement, find x

This implies that we keep guessing the values of x until we get a value that match the equation.

Let

$x = 625$

So, we have:

$x + 10\sqrt x = 1000$

$625 + 10 *\sqrt{625}$

Take the square root of 625

$625 + 10 *\sqrt{625} = 625 + 10 *25$

$625 + 10 *\sqrt{625} = 625 + 250$

$625 + 10 *\sqrt{625} = 875$

Let

$x = 729$

So, we have:

$x + 10\sqrt x = 1000$

$729 + 10 * \sqrt{729}$

Take the square root of 729

$729 + 10 * \sqrt{729} = 729 + 10 * 27$

$729 + 10 * \sqrt{729} = 729 + 270$

$729 + 10 * \sqrt{729} = 999$

At this point, we can conclude that x is approximately 729 because

$999 \approx 1000$

So:

$x \approx 729$

Which expression is equivalent to 8 times d times d

sveticcg [70]

Answer:

That is, they are equivalent expressions. Two expressions are said to be equivalent if they have the same value irrespective of the value of the variable(s) in them. Example 1: Are the two expressions 2y+5y−5+8 and 7y+3 equivalent?

What are three other ways to name? You may type or qx

Dominik [7]

A line can be named either using two points on the line (for example, ↔AB ) or simply by a letter, usually lowercase (for example, line m ). A line segment has two endpoints. It contains these endpoints and all the points of the line between them. You can measure the length of a segment, but not of a line.
