Find the value of f. What can you do to Both Sides?f - ⅔ = ¼
Thepotemich [5.8K]

Answer:

11/12

Step-by-step explanation:

<h2><u>Value of F </u></h2>

to find the value of f , we need to move the -2/3 to the other side of the equal sign.

f - \frac{2}{3}  = \frac{1}{4}

<u><em>Note </em></u>: is you move a number from one side of the equal sign to the other, this changes the sign of the number ( eg , -2/3 becomes +2/3)

f = \frac{1}{4}  + \frac{2}{3}

f = \frac{11}{12}

<h3><u>hence the value of f is  11/12 </u></h3>

Write a story that can be represented by the equation y=x+1/4x
makvit [3.9K]

This question is pretty much asking: Write a story that can be represented by the equation y=1.25x.

So, how about this one: Lily's mom tells Lily to clean up her toys. Lily puts toys away at a rate of one toy per every 1.25 seconds.

That's it, simple as that :P

The width of a rectangle is 2x + 4 and the length of the
iren [92.7K]

Given:

Width of a rectangle = 2x+4

Length of the rectangle = 6x+12

To find:

The ratio of the width to the length.

Solution:

We need to find the ratio of the width to the length.

\text{Required Ratio}=\dfrac{\text{Width}}{\text{Length}}

Putting the given values, we get

\text{Required Ratio}=\dfrac{2x+4}{6x+12}

\text{Required Ratio}=\dfrac{2(x+2)}{6(x+2)}

\text{Required Ratio}=\dfrac{2}{6}

\text{Required Ratio}=\dfrac{1}{3}

\text{Required Ratio}=1:3

Therefore, the ratio of the width to the length is 1:3.
