Answer:
There are 18 women in the class
Step-by-step explanation:
First of all this is a ratio topic and to solve it one needs to know that ratios are fractions so to solve it we will find first the sum of the fractions which is 3+1 and =4. Fully recognising through the question that the fractions or relation of the women to the men in the classroom is in a 3:1 ratio, we should multiply the fraction with the total number of people in the class which bring forth the result as 18!

Answer:
The simplest form is 2(3x - 7)/x(x³ + 4)
Step-by-step explanation:
* Lets revise how can divide fraction by fraction
- To simplify (a/b)/(c/d), change it to (a/b) ÷ (c/d)
∵ a/b ÷ c/d
- To solve it change the division sign to multiplication sign and
reciprocal the fraction after the sign
∴ a/b × d/c = ad/bc
* Now lets solve the problem
∵ 
- Lets take the denominator and simplify by make it a single
fraction, let the denominator of it 2x and change
the numerator
∴ 
∴ The fraction = 
* Now lets change it by (up ÷ down)
∴
÷ 
- Change the division sign to multiplication sign and reciprocal
the fraction after the sign
∴
× 
∴ 
- We can simplify x up with x down
∴ 
* The simplest form is 2(3x - 7)/x(x³ + 4)
The scientific notation used to write 1,000,000 would be 1 X 10^6.
1 X 10^6.
Take $65.95 times (0.0825) for the sales tax = 5.44
then, add the tax of $5.44 to the original amount of $65.95 = $75.39
