2/3 - 4x + 7/2 = -9x + 5/6 apply the properties.. step by step

Nutka1998 [239]

Answer:

x=5/13

Step-by-step explanation:

2/3+7/2=9x+5/6+4x

2/3+7/2-5/6=9x+4x

lcm of 2,3,6=6

2/3=4/6 7/2=21/6 5/6=5/6

4/6+21/6-5/6=9x+4x

30/6=13x

5=13x

x=5/13

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)

sydney is cutting the crust from the edges of her sandwich. the dimensions, in centimeters, of the sandwich is shown. which expr

hodyreva [135]

Here we can see that the problem gives us the length of a sandwich of x = 1.2. The problem also asks us for the expression that better represents the approximate length of the crust given among the options above. Here we simply have to substitute x to each of the choices.

The answer is B) x = 8x² + 34; 45.52 centemiters

I hope it helps, Regards.
