4 0

Answer:

x is the variable

Step-by-step explanation:

Given the following equation:

\frac{300+200}{x}

The term variable is basically a symbol or a letter that will change throughout the completion of a equation. In this case we are solving for x which means x is the letter/symbol that will change throughout the completion of this equation which means "the letter x is the variable."

Hope this helps.

A book sold 31,700 copies in its first month of release. Suppose this represents 8.8% of the number of copies sold to date. How
elena-14-01-66 [18.8K]

For this case we propose a rule of three:

31700 ------------> 8.8%

x ----------------------> 100%

Where "x" represents the number of copies sold to date.

x = \frac {100 * 31700} {8.8}\\x = \frac {3170000} {8.8}\\x = 360,227.273

Thus, to date 360,227 copies of the book have been sold.

ANswer:

To date, 360,227 copies of the book have been sold.

What is the molarity of a solution
Vika [28.1K]

Answer:

0.670. M

Step-by-step explanation:

Molarity can be expressed like this:

molarity =  number of moles /volume (L)

We know the volume, which is  2.37 L , but we need to find the number of moles. We can do this by dividing  67.3 g  by the molar mass of  L i C l :

number of moles  = mass of sample /molar mass

number of moles  =  67.3 g /(6.94 + 35.45) g/mol  = 67.3 g /42.39 g/mol

number of moles = 1.59 mol

molarity = 1.59 mol /2.37 L =  0.670. M
