12/x+5
x represents “a number” because it’s unknown and the + sign is because the words sum
Answer:
<h2>The price is 860 dollars.</h2>
Step-by-step explanation:
The revenue of the company is given by 
, which is a polynomial of x, the price of the new phone.
The revenue of the company will be the highest, if 
, that is
1720 - 2x = 0
or, x = 860.
Hence, the price of the new phone to maximize the company's revenue is 860 dollars.
Answer:
the sum of all three angles is 180° in every plane triangle.
knowing that we know that the upper right angle is 180-99-37 = 44
do it follows:
-x-5 = 44
and
-x = 49
and there
x is -49

2)The goal is to isolate the variable and get is down to x<?. This is actually a two step inequality problem. 0.7x - 2 < 5.5 +2 +2 0.7x<7.5 This implies: x<10.714 The way to graph this is to place an open circle of the number 10.714 on the number line indicating this number is not included as a solution to the inequality. Then draw the arrow going left from the open circle indicating all numbers from -∞ to 10.714.
