Answer:

The other rational number is \dfrac{14}{27}.

Step-by-step explanation:

First rational number is \dfrac{-2}{3}

Let other rational number is \dfrac{x}{y}

The product of two rational numbers is \dfrac{-28}{81}

According to question,

\dfrac{x}{y}\times \dfrac{-2}{3}=\dfrac{-28}{81}

Multiplying both sides by (-3/2) such that,

\dfrac{x}{y}\times \dfrac{-2}{3}\times \dfrac{-3}{2}=\dfrac{-28}{81}\times \dfrac{-3}{2}\\\\\dfrac{x}{y}=\dfrac{14}{27}

So, the other rational number is \dfrac{14}{27}.

Solve for f: 6f + 9g = 3g + f
lozanna [386]
Hi there!

Let's solve this equation step by step!
6f + 9g = 3g + f

To solve for f, we need to bring all the terms in the equation with an f in it to the left, and all the other terms (with a g) to the right.

First subtract f from both sides.
5f + 9g = 3g

Now subtract 9g from both sides.
5f = -6g

And finally divide both sides by 5.
f = (-6/5)g

Hence, your answer;
f =  -  \frac{6}{5} g

~ Hope this helps you!

A cheetah ran 300 feet in 2.92 secods. What was the cheetahs average speed in miles per hou? Show your work.
Tom [10]
Start by converting 300 feet to miles and 2.92 seconds to hours.

300 feet      1 mile
----------- x -------------- = ?
     1           5280 feet

2.92 sec              1 hr
----------------- * ---------------- =  ?
        1               3600 sec

Reduce each of the above fractions.  Then convert  300 feet
                                                                                  -------------- to the 
                                                                                    2.92 sec

equivalent speed / rate in mph using the converstion factors you derived earlier.
