5n+24=|8-3n|\\
5n+24\geq0\\
5n\geq-24\\n\geq-\dfrac{24}{5}\\
8-3n=5n+24 \vee 8-3n=-5n-24\\
8n=-16 \vee 2n=-32\\
n=-2 \vee n=-16\\\\
-16\not\geq-\dfrac{24}{5} \Rightarrow \boxed{n=-2}

\hbox{the domain:} \\
5n+24 \geq 0 \\
5n \geq -24 \\
n \geq -\frac{24}{5} \\
n \geq -4 \frac{4}{5}

5n+24=|8-3n| \\
5n+24=8-3n \ \lor \ -(5n+24)=8-3n \\
5n+3n=8-24 \ \lor \ -5n-24=8-3n \\
8n=-16 \ \lor \ -5n+3n=8+24 \\
n=-2 \ \lor \ -2n=32 \\
n=-2 \ \lor \ n=-16

n=-2 \geq -4 \frac{4}{5} \hbox{ - it is a solution} \\&#10;n=-16 < -4 \frac{4}{5} \hbox{ - it isn't a solution} \\ \\&#10;\boxed{n=-2}

6x-2y=24<br> how do u solve for y
Tatiana [17]
It's <span>Diophantine equation. 
First, we need to found gcd(6,(-2)):</span>
6=2*3
(-2)=(-1)*2

So, gcd(6,-2)=2
Now, the question is. Can we dived c=24, by gcd(6,-2) and in the end get integer?
Yes we can.
\frac{24}{2} =12
So, we can solve it.

Now is the formula:
{\displaystyle {\begin{cases}x=x_{0}+n{\frac {b}{\gcd(a,\;b)}}\\y=y_{0}-n{\frac {a}{\gcd(a,\;b)}}\end{cases}}\quad n\in \mathbb {Z} .}

Second, we need the first pair (x0,y0) 
 if
x=0
then
y=(-12)

Third, we gonna use that formula:
{\displaystyle {\begin{cases}x=-n}\\y=-3(4+n)}\end{case}\quad n\in \mathbb {Z} .}
Congratulations! We solve it.

You surveyed 112 students and found out that 14 went to the movies last week-
Cerrena [4.2K]

Answer:

c) 325

Step-by-step explanation:

The fraction of students that went to the movies is 14/112. To find the number of students who went to the movies from a larger group, you have to find a fraction equal to 14/112, whose denominator is 2600 (the number of students from the larger group).

14/112 = x/2600

You can do cross multiplication here. Cross multiplication is multiplying the denominator of one fraction by the numerator of the fraction equivalent to it. That product will be equal to the numerator of the first fraction * denominator of the second fraction.

112*x = 14*2600

x = 325

Approximately 325 students out of 2600 students would've gone to the movie last weekend.
