A schools enrollment in 2012 was 1234 now it is 1456 what does the expression look like that would help me find the percent chan

astraxan [27]

Answer:

.18 % increase

Step-by-step explanation:

First you would find what the difference is between the school enrollment

you would do 1456 - 1234 = 222

Then you would divide 1234/1456 = 84.75% to see the total percentage

The increase however has a percentage of .18%

To check your work you would do .18 x 1234 = 222.12 ( round to the nearest whole number so it would just be 222) then add 1234+ 222 = 1456!

The variables y and x have a proportional relationship, and y = 9 when x = 2.

Aloiza [94]

Answer: $y=13.5$

Step-by-step explanation:

1. By definition, if $y=9$ when $x=2$ , then:

$\frac{y}{x}=\frac{9}{2}$

2. Keeping this on mind, to find the value of $y$ when $x=3$ , you must apply the following proccedure:

$\frac{y}{3}=\frac{9}{2}$

3. Now, you must solve for $y$ , as following:

$y=3(\frac{9}{2})\\y=\frac{27}{2}\\y=13.5$

4. Then, the result is:

$y=13.5$

Solve the equation and show all work. 4|x + 1/3| = 20 <br> i'm kind of stuck hhh

Absolute value is a function that takes some number and outputs the size of that number, regardless of the sign. By definition, $|x|=x$ if $x\ge0$ , and $|x|=-x$ if $x$ .

For example,

|2| = 2 because the input 2 is positive, so the input is unchanged;
|-3| = -(-3) = 3 because the input -3 is negative, so the sign is switched.

What this means for this problem is that there are two cases to consider:

If $x+\frac13\ge0$ , then $\left|x+\frac13\right|=x+\frac13$ , so that

$4\left(x+\dfrac13\right)=20\implies x+\dfrac13=5\implies\boxed{x=\dfrac{14}3}$

On the other hand, if $x+\frac13$ , then $\left|x+\frac13\right|=-\left(x+\frac13\right)$ , so

$-4\left(x+\dfrac13\right)=20\implies x+\dfrac13=-5\implies\boxed{x=-\dfrac{16}3}$
