Answer:

x = 4

Step-by-step explanation:

Given

13 - 4x = 1 - x ( add x to both sides )

13 - 3x = 1 ( subtract 13 from both sides )

- 3x = - 12 ( divide both sides by - 3 )

x = 4

Given the coordinates below, what is the midpoint of AB?<br> A(-6, -10)<br> B(2,5)

madreJ [45]

Given :

$\:$

A(-6, -10)
B( 2, 5)

$\:$

$\gray{ \frak{The \: given \: two \: \: points \: are(x_{1 },y_{1})=(−6 , -10)and(x_{ 2 },y_{2} )=( 2,5 )\:}}$

$\:$

Let's solve by using midpoint formula :

$\:$

$\bf \boxed{\color{red}\frak{Midpoint \: \: Formula : {( \: x ,\:y \: ) = }( \frak{ \frac{x_{1 } + y_{1}}{2} , \frac{x_{2 } + y_{2}}{2} )}}}$

$\:$

$\large \gray{ \frak{( \: x ,\:y \: ) = }( \frak{ \frac{ -6 + 2}{2} , \frac{ - 10 + 5}{2} )}}$

$\:$

$\: \large \gray{ \frak{( \: x ,\:y \: ) = }( \frak{ \frac{ -4}{2} , \frac{ - 5}{2} )}}$

$\:$

$\large \gray{ \frak{( \: x ,\:y \: ) = }( \frak{ \cancel\frac{ -4}{2} , \cancel\frac{ - 5}{2} )}}$

$\: \:$

$\underline{ \boxed{ \large \red{ \frak{option \: d }( \frak{ - 2, - 2.5)}}}}✓$

Hope Helps! :)

O 12 Ms. Ruby has 1 beanbag chair in her room. She lets 4 students take equal turns sitting in the chair during a 38-minute read

My name is Ann [436]

The number of students allowed to sit, N=4.

The total number of minutes, T=38 minutes.

Let x be the number of minutes for a student

$\begin{gathered} 4\text{ students-}\longrightarrow38\text{ minutes} \\ 1\text{ student--x} \\ \text{Cross multiplying,} \\ x=\frac{38\text{ minutes}}{4\text{ students}}\times1\text{ students} \\ =\frac{38}{4\text{ }}\text{minutes} \end{gathered}$
