9x-23=49 what is the second step in this equation?
ladessa [460]

Answer:

Divide both sides by 9.

Step-by-step explanation:

To find the second step of the equation, we actually have to solve parts of the equation until we get to step 2.

Step 1: Add 23 to both sides.

  • 9x - 23 + 23 = 49 + 23
  • 9x = 72

Step 2: Divide both sides by 9.

  • \frac{9x}{9} = \frac{72}{9}
  • x = 8

Therefore, the second step is divide both sides by 9.

A symbol used to name one or more parts of a whole or a set, or a location on a number line is a?​
jeka94

Answer:

Fraction

Step-by-step explanation:

Fraction is a symbol that represents a part of a whole. It consists of a <em>numerator</em> and a <em>denominator. </em>The numerator is the number above the fraction bar (also known as "Vinculum), while the denominator is the number below the fraction bar. The denominator is the total number of equal parts in a whole.

Examples of Fraction: \frac{1}{2}, \frac{2}{7} and \frac{5}{8}.

In the first example, \frac{1}{2}, 1 is the numerator, while 2, is the denominator.

<u>Additional Information</u>

When the numerator is smaller than the denominator, the fraction is called <em>"proper fraction."</em> On the contrary, when the numerator is bigger than the denominator, the fraction is called <em>"improper fraction."</em>
