Answer:
$9426.50
Step-by-step explanation:
let noel's salary = x, robert's salary = y and john's salary = z
y = x - 512.75 ..........(1)
z = 3y = 3(x - 512.75) = 3x - 1538.25 ...............(2)
x + y + z = 47645.25..........................(3)
substitute for y and z
x + (x - 512.75) + (3x - 1538.25) = 47645.25
x + x - 512.75 + 3x - 1538.25 = 47645.25
5x = 47645.75 + 512.75 + 1538.25
5x = 49696.25
divide both sides by 5
x = 9939.25 ..... noel's salary
to get robert's salary substitute x in equation 1
y = 9939.25 - 512.75 = 9426.50
y = $9426.50..... robert's salary
Answer:
So for the first one the first ting u have to do is FLIP the equation so---> X-12=y
Then you have to add 12 to BOTH sides----> x-12+12=y+12
<u><em>So your answer for X ----> x=y+12</em></u>
<u><em>For Y on the first equation it is--->y=x-12</em></u> (Just flipped and the sign changed)
For the second equation we are gonna solve for Y first.
The first thing u want to do is divide both sides by -3 so it will look like this
-3y/-3 = 2x/+36/-3
<u><em>So Y will equal-----> -2/3x- 12</em></u>
Now we are going to do the X part
So fist FLIP the equation----> 2x+36= -3y
The add -36 to both sides-----> 2x+36+-36=-3y+-36
Last step you have to divide both sides by 2
So that would be----> 2x/2= -3y-3
<u><em>Your final result will be----> x=-3/2y-18</em></u>

Answer:
X= Gracie
X+7.2=Hilda
X+7.2-11.4=Janell
(X+X+X+7.2+7.2-11.4)÷3=62.6
(3x+3)÷3=62.6
3X+3=187.8 (I arrive at 187.8 because I multiple 62.6 by 3)
3X=187.8-3
3X=184.8
3X/3=184.8/3
X=61.6
Step-by-step explanation:
GRACIE X=61.6
Hilda X+7.2=61.6+7.2=68.8
Janell X+7.2-11.4=61.6+7.2-11.4= 57.4
The example in that question, the age of Roger is the independent variable. This means that the variable left is <span>granola bars. This make it the dependent variable since it depends on the age of Roger.
The age does not depend on the amount of </span>granola bars eaten by Roger but the amount of <span>granola bars may depend with age of Roger.</span>
