if the cost of a dress is multiplied by 5/8 the price then becomes $30.00 what was the original price
Alik [6]
Let's label the original price of the dress as x. We know that
x \times  \frac{5}{8}  = 30
so that means that we can find x by dividing both sides by 5/8:
x = 30   \div  \frac{5}{8}
A simple rule for dividing fractions is 'Keep Change Flip'. You keep the first number/fraction the same, you change the ÷ to a × and you flip the second fraction. Through this rule, we can now solve the equation much more easily:
x = 30 \times  \frac{8}{5}  \\ x =  \frac{240}{5} \\ x = 48
Therefore, the original price of the dress was $48

Show all work to factor x4 – 10x^2 + 9 completely.
iragen [17]

Answer:

(x+1)(x-1)(x+3)(x-3)

Step-by-step explanation:

it is a fourth degree trinomial

1) find two number whose sum is -10 and whose product is 9

the two numbers are -1 and -9

2) write the trinomial as a multiplication in this way

(x^2-1)(x^2-9)

3) the two factors are both a difference of tho squares.

so we can rewrite it as

(x+1)(x-1)(x+3)(x-3)

Answer:

\large\boxed{\dfrac{x^3+6x}{80x+64}}

Step-by-step explanation:

\dfrac{\frac{1}{8}+\frac{x+4}{16}}{\frac{x+4}{x^2}+\frac{4}{x}}=\left(\dfrac{1\cdot2}{8\cdot2}+\dfrac{x+4}{16}\right):\left(\dfrac{x+4}{x^2}+\dfrac{4\cdot x}{x\cdot x}\right)\\\\=\left(\dfrac{2}{16}+\dfrac{x+4}{16}\right):\left(\dfrac{x+4}{x^2}+\dfrac{4x}{x^2}\right)=\dfrac{2+x+4}{16}:\dfrac{x+4+4x}{x^2}\\\\=\dfrac{x+6}{16}:\dfrac{5x+4}{x^2}=\dfrac{x+6}{16}\cdot\dfrac{x^2}{5x+4}=\dfrac{(x+6)(x^2)}{(16)(5x+4)}\\\\\text{use distributive property}\ a(b+c)=ab+ac

=\dfrac{(x)(x^2)+(6)(x)}{(16)(5x)+(16)(4)}=\dfrac{x^3+6x}{80x+64}
