<h3>to understand this</h3><h3>you need to know about:</h3>

linear equation
PEMDAS

<h3>tips and formulas:</h3>

$\sf\text{a system of linear equation has only one solution if $\frac{a_1}{a_2}\neq \frac{b_1}{b_2}$}$

<h3>given:</h3>

$\begin{cases}2x - 4y = - 1 \\ 8x - 11y = - 19 \end{cases}$

<h3>let's solve:</h3>

$\sf substitute \: the \: value \: of \: a \: b : \\ \frac{2}{8} \ne \frac{ - 4}{ - 11} \\$

$\text{$\therefore$ the system of linear equation has only one solution}$

Artist 52 [7]

Answer: (B) 20 or (C) 24 <em>depending on which number was erased</em>

<u>Step-by-step explanation:</u>

The median is the middle number of the set <em>in order from least to greatest</em>

{18, 30, 26, 12, 22}

First, put the set in order from least to greatest: {12, 18, 22, 26, 30}

Next, find the middle number by crossing out the end numbers:

{12, 18, 22, 26, 30}
{X, 18, 22, 26, X}
{X, X, 22, X, X}

The median of the given set is 22. Since a number was erased, then the median has to be the average of the two middle numbers.

If the erased number is on the left side {?, 12, 18, 22, 26, 30}, then the median is the average of 18 and 22, which is 20

If the erased number is on the right side {12, 18, 22, 26, 30, ?}, then the median is the average of 22 and 26, which is 24

Kenisha tried to subtract two polynomials her work is shown below. At which step did Kenisha make an error, If at all?

inysia [295]

Answer:

Step 1

Step-by-step explanation:

When you subtract a polynomial in parentheses, you have to remove them from the parentheses first, which Kenisha did right. The problem is that because the numbers are being subtracted, <em>all of the signs switch</em>, which they forgot to do. Step one should look like: 2b² + 3b + 11 <em>- 7b² + 5b - 1</em>

Density is the ratio of mass to volume 83 l jug of honey has amassed a 4.5 kg

marta [7]

Density is mass (g) over volume (mL) if the 83 is in mL then

4.5 kg converted to g = 4500
