Answer:

The equation to represent total number of pencils p that Rafael bought is 15 n .  

Step-by-step explanation:

Given as :

The total numbers of pencils packs bought by Rafael = n

The number of pencils in each pack = 15 pencils

Let The total number of pencil does Rafael bought = p

<u>Now, According to question</u>

The total number of pencil does Rafael bought =  total numbers of pencils packs bought by Rafael × number of pencils in each pack

i.e p = n × 15

So, The  total number of pencil does Rafael bought = p = 15 n

Hence, The equation to represent total number of pencils p that Rafael bought is 15 n .  Answer

General Formulas and Concepts:

<u>Pre-Algebra</u>

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality<u> </u>

<u>Algebra I</u>

  • Factoring

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

\displaystyle 10 = ax + bx

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Factor:                                                                                                               \displaystyle 10 = ax + bx \rightarrow 10 = x(a + b)
  2. [Division Property of Equality] Divide a + b on both sides:                           \displaystyle 10 = ax + bx \rightarrow x = \frac{10}{a + b}

Compute x/y if
Ivenika [448]

Answer:

Y = 1/4x-1

X = 4y-1

Step-by-step explanation:

layout the equations :

x+1/y = 4        y+1/x = 1/4

solve the equations, remember to switch sides switch signs solving the equations will give us the value of the letter

x+1/y = 4

x+1 = 4y

x=4y-1

***

y+1/x = 1/4

y+1  = 1/4x

y = 1/4x-1
