<h3><u>Answer</u>:- </h3>

\longrightarrow \sf  2\dfrac{1}{20}

<h3><u>Solution:-</u></h3>

\begin{gathered}\\\implies\quad \sf 4 \frac{1}{10} \div 2 \\\end{gathered}

<u>Converting to mixed fraction-</u>

\begin{gathered}\\\implies\quad \sf  \frac{4\times 10+1}{10} \div 2 \\\end{gathered}

\begin{gathered}\\\implies\quad \sf  \frac{41}{10} \div 2 \\\end{gathered}

\begin{gathered}\\\implies\quad \sf  \frac{41}{10} \div  \frac{2}{1} \\\end{gathered}

\begin{gathered}\\\implies\quad \sf  \frac{41}{10} \times   \frac{1}{2} \\\end{gathered}

\begin{gathered}\\\implies\quad \sf  \frac{41}{20} \\\end{gathered}

<u>Writing final answer again in mixed form </u>

\begin{gathered}\\\implies\quad \sf  2\frac{1}{20} \\\end{gathered}

Solve quadratic equation (x-3)^2+5=14
loris [4]
(X-3)^2+5=14
Step 1: simplify both sides of the equation
X^2-6x+14=14

Step 2: subtract 14 from both sides
X^2-6x+14-14=14-14
X^2-6x=0

For this equation: a=1, b=-6,c=0
1x^2+-6x+0=0

Step 3: Use quadratic formula with a=1, b=-6, c=0

The answer is x=6 or x=0

−k−(−8k) Combining like terms im confused!
melisa1 [442]

-k-(-8k)

= -k + 8k (two negatives equal one positive)

= 8k-k (flip it around because of the commutative property)

=7k (basic subtraction)

I really hope that helped :)

1. |4n-15|=|n|<br> 2. |2c+8|=|10c| <br> can you please show the work for both
Alja [10]

Problem 1

<h3>Answers: n = 3 or n = 5</h3>

---------------

Work Shown:

|4n - 15| = |n|\\\\4n - 15 = n \ \text{ or } \ 4n-15 = -n\\\\-15 = n-4n \ \text{ or } \ -15 = -n-4n\\\\-15 = -3n \ \text{ or } \ -15 = -5n\\\\-3n = -15 \ \text{ or } \ -5n = -15\\\\n = \frac{-15}{-3} \ \text{ or } \ n = \frac{-15}{-5}\\\\n = 5 \ \text{ or } \ n = 3\\\\

==============================================

Problem 2

<h3>Answers: c = 1 or c = -2/3</h3>

-----------------------

Work Shown:

|2c+8| = |10c|\\\\2c+8 = 10c \ \text{ or } \ 2c+8 = -10c\\\\8 = 10c-2c \ \text{ or } \ 8 = -10c-2c\\\\8 = 8c \ \text{ or } \ 8 = -12c\\\\8c = 8 \ \text{ or } \ -12c = 8\\\\c = \frac{8}{8} \ \text{ or } \ c = \frac{8}{-12}\\\\c = 1 \ \text{ or } \ c = -\frac{2}{3}
