Statements: Reasons:

1) ∠2 and ∠4 are vertical angles given

2) limes m and n intersect at P definition of vertical angles

3) ∠3 and ∠4 are linear pair definition of linear pair

4) ∠2 and ∠3 are linear pair definition of linear pair

5) m∠3 + m∠4 =180 angle addition postulate

6) m∠2 + m∠3 =180 angle addition postulate

7) m∠2 + m∠3 = m∠3 + m∠4 substitution property

8) m∠2 = m∠4 subtraction property

9) ∠2 ≅ ∠4 definition of congruent(≅) angles

There are 53 regular pencils in the box and some colored pencils in the box. There are a total of 84 pencils. How many colored p

vodka [1.7K]

Let be "x" the number of colored pencils in the box.

According to the information given in the exercise, there are 84 pencils in the box and 53 of them are regular pencils.

Knowing this information, you can set up the following equation:

$x+53=84$

Finally, you have to solve for the variable "x" in order to find its value. In order to do this, you can apply the Subtraction property of equality by subtracting 53 from both sides of the equation:

$\begin{gathered} x+53-(53)=84-(53) \\ x=31 \end{gathered}$

The answer is: There are 31 colored pencils in the box.
