Moby sold half his toy car collection, and then bought 12 more cars the next day. He now has 48 toy cars. How many cars did he h
castortr0y [4]

Answer: 72 cars.

Step-by-step explanation:

Let be "x" the number of toys that Moby had to start with.

According to the information given in the exercise, Moby sold half his toy car collection. This can be represented with the following expression:

\frac{1}{2}x

Then he bought 12 more cars, giving a total amount of 48 toy cars.

Therefore, the equation that represents this situation is the equation shown below:

x-\frac{1}{2}x+12=48

Now you must solve for "x" in order to find its value.

You get that this is:

\frac{1}{2}x+12=48\\\\\frac{1}{2}x=48-12\\\\\frac{1}{2}x=36\\\\x=(36)(2)\\\\x=72

84% 84, percent of astrid's books are fiction. What fraction of astrid's books are fiction?
yuradex [85]

Let number of  books by astrid's = x

Out of x , 84% are fiction.

So, Number of non fictional books = x - \frac{84x}{100}

                                       =  \frac{100x- 84 x}{100} =  \frac{16x}{100}

→Ratio of number of  books to  fictional books

                                     =\frac{x}{\frac{84x}{100}}\\ = \frac{100}{84}\\= \frac{25}{21}⇒[Dividing numerator and denominator by 4.]

→Out of 25 books by astrid 21 are fictional.

→ Number of fictional books by astrid = \frac{21}{25}

Total number of columns = 10

Total boxes = 100

Shaded boxes = 72

We calculate %age by,

=> Selected boxes/Total boxes x 100

=> 72/100 x 100

=> 72%
