I hope I read it correctly and address as such.
Anywho, this is how my teacher taught me to deal with a question like that. Basically just break up the polynomial on top and divide each part separately by the monomial denominator.
The answers to the questions
We are given that popularity of television is inversely proportional to its cost.
let us say popularity of television is represented by "P" and cost of television by "T".
We will use a constant "k" to convert the proportionality sign to equal to (=) sign.
Thus forming the equation :
![P= \frac{k}{T}](https://tex.z-dn.net/?f=%20P%3D%20%5Cfrac%7Bk%7D%7BT%7D%20%20)
We are given that 15 customers buy a television that cost $1500.
plugging P=15 and T=1500, finding k,
![15= \frac{k}{1500}](https://tex.z-dn.net/?f=%2015%3D%20%5Cfrac%7Bk%7D%7B1500%7D%20%20)
k=15*1500 = 22500
Next we have to find how many customers would buy a television that costs $2500, so here k=22500 and T=2500, plugging this in the equation we have ,
![P= \frac{22500}{2500}](https://tex.z-dn.net/?f=%20P%3D%20%5Cfrac%7B22500%7D%7B2500%7D%20%20)
P=9
So there will be 9 customers that buy a television which costs $2500.
First, 81/1.5 = 54
54 x 1 = 54
54 dollars
Answer:
x= 10
Step-by-step explanation:
A triangle always sums up to 180 degrees. (Remember this)
So, tha equation would be: 73+(4x-1)+(6x+8)= 180.
Step 1- Add common variables.
(4x+6x)+73+8-1= 180
10x+73+8-1= 180
Step 2- Add to simplify.
10x+(73+8-1)= 180
10x+80= 180
Step 3- Subtract 80 to both sides.
10x+80= 180
-80 -80
10x= 100
Step 4- Divide both sides by 10.
<u>10x</u>= <u>100</u>
10 10
x= 10
