Answer:
The answer is:
She used the wrong common denominator
Step-by-step explanation:
Solving the given equation

Lets consider the steps given in the question:


Lets compare both solutions:
In the original solution, the denominator of first term is (x-2)(x-3)
In the solution given in the question, the denominator of first term is (x-2)(x+3).
So the mistake she did in step 2 was that she change the sign of 3 in (x-3) from negative to positive, due to which she gets the wrong common denominator shown in Step 3.

Answer:
0.0286 or 2.86%
Step-by-step explanation:
The total number of people that have werewolfism is 21,000.
Of those 21,000, 600 also have vampirism, while the remaining 20,400 do not. Therefore, the probability that someone has vampirism, given that they have werewolfism is:

The probability is 0.0286 or 2.86%.
$137.5 is the money does Nancy have.
<u>Step-by-step explanation:</u>
The given information are,
- Steve has a total money = 55
- Nancy has a money = 250% as much money as Steve.
We know that, from the given data the money that Steve has is 55.
This means that, Nancy has money = 250% of 55.
Let us assume,
x be the total money that Nancy have.
Therefore, x = 250% of 55.
The percentage can be represented as 1 divided by 100.
⇒ x = (250 × 1/100) × 55
⇒ x = 2.5 × 55
⇒ x = 137.5
The money does Nancy have is 137.5
Answer:
The mystery number is 7
Step-by-step explanation:
This is a very easy problem.
let the mystery number=x
2(x+5)=24
2x+10=24
2x=24-10
2x=14
x=7
To check the answer,
Add 5 to 7=12, multiply by 2=24
