Only 4,52 would be on the graph.
If she stated at week 0 with 32 dollars it would be:
0, 32
1, 37
2, 42
3, 47
4, 52
5, 57
6, 62
7, 67
and so on.

4,52 becouse the equation is
32+5x=y
so you replace and find ourlt tha 4 ,52 is right

In a class of 24 people, the ratio of women to men is 3 to 1. How many women are in the class?
ryzh [129]

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!

Simplify the complex fraction
andrew11 [14]

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

∵ \frac{\frac{3x-7}{x^{2}}}{\frac{x^{2}}{2}+\frac{2}{x}}

- Lets take the denominator and simplify by make it a single

 fraction, let the denominator of it 2x and change

 the numerator

∴ \frac{x^{2}}{2}+\frac{2}{x}=\frac{x(x^{2})+2(2)}{(2)(x)}=\frac{x^{3}+4}{2x}

∴ The fraction = \frac{\frac{3x-7}{x^{2}}}{\frac{x^{3}+4}{2x}}

* Now lets change it by (up ÷ down)

∴ \frac{3x-7}{x^{2}} ÷ \frac{x^{3}+4}{2x}

- Change the division sign to multiplication sign and reciprocal

 the fraction after the sign

∴ \frac{3x-7}{x^{2}} × \frac{2x}{x^{3}+4}

∴ \frac{(2x)(3x-7)}{(x^{2})(x^{3}+4)}

- We can simplify x up with x down

∴ \frac{2(3x-7)}{x(x^{3}+4)}

* The simplest form is 2(3x - 7)/x(x³ + 4)
