How to solve 1/4-x=x/8

Mathematics

Contact [7]3 years ago

Answer:

x=\frac{2}{9}

Step-by-step explanation:

\frac{1}{4}-x=\frac{x}{8}

  • With the equation's current format, we will have trouble solving with all these fractions. Especially the fraction \frac{x}{8} is very difficult to deal with, so my first step would be:

(\frac{8}{1})(\frac{1}{4}-x)=\frac{x}{8}(\frac{8}{1})

  • If we multiply both sides by this number, we will be able to get rid of the messy fraction on the right side as well as remove the fraction on the left side. Like so:
  • <em>I put the 8 I multiplied onto each side in fraction form simply for clarity. You do not need to do this.</em>

(\frac{8}{1})(\frac{1}{4}-x)=\frac{x}{8}(\frac{8}{1})\\\frac{8}{4}-8x=\frac{8x}{8}\\2-8x=x

  • After this point, let's put our variable, x, onto one side of this equation and any other integers on the other by adding and subtracting them from both sides.

2-8x=x\\-9x=-2

  • Now we divide so that x is isolated, and we are done.

x=\frac{-2}{-9}=\frac{2}{9}

If the result is reflected over x-axis and vertically stretched by a factor of 5, the result will be g(x) = -5(x - 1)²

<h3>Transformation of functions</h3>

Transformation is a way of changing the position of an object o the xy plane. Given the parent function expressed as

f(x) = x^2

If the function is shifted to the left by unit, then we will have h(x) = (x - 1)²

If the result is reflected over x-axis and vertically stretched by a factor of 5, the result will be g(x) = -5(x - 1)²

Solve for the variable 7/28 = 25/?
ICE Princess25 [194]
Let x be the unknown number. The equation is going to be 7/28=25/x, now we cross multiply. 7*x=25*28, 7x=700, divide both sides by 7 and you should get 100, So, x=100 and 7/28=25/100

Paula purchase 3 dvd and 7 cds and spent between 90 and 100. Each dvd costs the same amount the price of cd is 10 select all amo
sveticcg [70]

The options aren't given, however, the range of amount spent could be calculated

Answer:

Kindly check explanation

Step-by-step explanation:

Paula purchase 3 dvd and 7 cds and spent between 90 and 100. Each dvd costs the same amount the price of cd is 10 select all amounts that could be the price of the dvd

Given that :

DVD costs the same amount

Number of DVD's = 3

Cost of cds = 10

Number of cds = 7

Total cost of cd's = 10 * 7 = 70

Let the price of DVD = x

Total amount spent = 90 - 100

Lowest price of DVD :

(amount spent - price of cd) / number of dvd

(90 - 70) / 3 = 20 /3 = 6.667

Highest price :

(100 - 70) / 3 = 30 / 3 = 10

Hence the pice of each DVD will range between /

6.6666 and 10.

Hence, prices listed within the range above are possible.
