Answer:

$599

Step-by-step explanation:

Given: Discount- 40% off on original price.

           Gift card= $25

           Total cost before taxes is $334.40

Lets assume the original price be "x".

We know there is 40% on original price and Perry uses $25 gift card.

Remember; Total cost= Original\ price- discount- gift\ card

Now, finding the original price of Iphone.

⇒ x-0.40x-25= 334.40

⇒ 0.60x-25= 334.40

Adding both side by 25

⇒0.60x= 334.40+25

⇒0.60x= 359.4

Dividing both side by 0.60

⇒ x= \frac{359.4}{0.60}

∴ x= 599

Hence, the original price of iphone is $599

G=x-c/x. for x<br><br>how do yoy make this an equation for x? help
zzz [600]
1.
\displaystyle \text{if }\quad G=x-  \frac{C}{x} \\\\

x \neq 0

Multiply both sides by x:

\displaystyle Gx=x\bigg(x- \frac{C}{x}\bigg )\\\\Gx=x^2-C

Subtract from both sides Gx:
Gx-Gx=x^2-C-Gx\\x^2-Gx-C=0

Then solve this equation:

\displaystyle x^2-Gx-C=0\\\\x_{1,2}= \frac{G\pm  \sqrt{G^2+4C} }{2}

2.
\displaystyle\text{if}\quad G= \frac{x-C}{x}

x \neq 0

Multiply both sides by x:

Gx=x-C

Subtract from both sides Gx:

x-C-Gx=0

Then solve this equation:

\displaystyle x-Gx-C=0\\x(1-G)=C\\x= \frac{C}{1-G}

Hello, can you please express this without denominators with the work?
Lena [83]
\bf  a^{-{ n}} \implies \cfrac{1}{a^{ n}}\qquad \qquad&#10;\cfrac{1}{a^{ n}}\implies a^{-{ n}}&#10;\\ \quad \\&#10;%  negative exponential denominator&#10;a^{{ n}} \implies \cfrac{1}{a^{- n}}&#10;\qquad \qquad &#10;\cfrac{1}{a^{- n}}\implies \cfrac{1}{\frac{1}{a^{ n}}}\implies a^{{ n}} \\\\&#10;-----------------------------\\\\&#10;\cfrac{4xy}{mn^5}\implies \cfrac{4xy}{1}\cdot \cfrac{1}{m^1}\cdot \cfrac{1}{n^5}\implies 4xym^{-1}n^{-5}

notice, all you do is, move the factor from the bottom to the top, or from the top to the bottom, and the sign changes, from negative to positive or the other way around, is all there's on that
