25. The product of 8 and the difference between a number and 9 is 96. What is the number?
The answer is 13. 
So, 8*(x-9)=96
8*12=96
So, what number minus 9=12? 13.

26. When 12 is added to half the sum of a number and 8, the result is 40. What is the number?
The answer is 40.
12+ (x+8)=40
12 +28=40, so what plus 8 =28? 20. 
20 times 2 is 40.

27. The difference between a number and 5, when multiplied by 3, is 36. What is the number?
The answer <em />is 17.
(x-5)*3=36
12*3=36, so what minus 5=12? 17.

From 19801980 to 20002000, the annual profit of a company was determined by subtracting from \$625{,}000$625,000 the product of
igor_vitrenko [27]

Answer: b) 625 - 25 |x - 1990| = 550

Step-by-step explanation:

According to the question,

The annual profit of a company was determined by subtracting from $625,000 the product of $25,000 and the number of years either before or after 1990.

That is, On  x year the total profit is,

P(x) =  625,000 - 25,000 |x - 1990|

But again according to the question,

On x years the profit is $ 550,000

Thus, 625,000 - 25,000 |x - 1990| = 550,000

⇒ 625 - 25 |x - 1990| = 550 ( by dividing both sides by 1000)

Therefore, Option b) is correct.

Simplify |x| - |-x|.
Verdich [7]

Answer:

0

Step-by-step explanation:

Two cases: if x\ge0

|x| - |-x| = x - x= 0

Instead if x

|x| -|-x| = -x -(-x)=-x+x=0

Alternatively you can try to graph both f(x) = |x|; g(x)=|-x| and checking the vertical distance between the two graphs
