When you're finding equivalent fractions, the best thing to do is to multiply the numbers.
2/6 is also equal to 1/3
2/6 is equal to 4/12
2/6 is equal to 6/18
2/6 is equal to 8/24
Hope this helps :)

4a. In a book store, for every 9 books sold, 13 magazines were sold. If they had a 572 sales, how many of the sales were for boo

topjm [15]

Answer:

234 books.

Step-by-step explanation:

You need to set up a proportion. Be careful to note what it looks like and the explanation that follows.

9 books 13 magazines

======= = ===========

x 572 - x Cross multiply

What you want is the number of book sales from the proportion.

However all you have is the ratio of books to magazines. So you have to set up the total sales to magazines, which is a bit awkward. 572 - x is the number of magazine sales.

9*(572 - x) = 13x Remove the brackets on the left.

5148- 9x = 13x Add 9x to both sides.

5148 = 13x + 9x Transpose and add the right.

22x = 5148 Divide by 22

x = 5148/22

x = 234

234 books were sold.

Sam has twice as many books as Jim. If Sam gives 12 books to Jim, they will have the same number of books. How many books do the

Neko [114]

Alright, lets get started.

Suppose number of books Jim have = x

Sam has twice as many books as Jim. So,

Number of books Sam have = 2x

If Sam gives 12 books to Jim, they will have the same number of books.

When Sam gives 12 books, his remaining books will be $= 2x - 12$

When Jim gets 12 books from Sam, his books will be $= x + 12$

And as per given question, they both now have equal books, so

$2x - 12 = x + 12$

Adding 12 in both sides

$2x - 12 + 12 = x + 12 + 12$

$2x = x + 24$

Subtracting x from both sides

$2x - x = x + 24 - x$

$x = 24$

It means Jim has number of books = 24

So, Sam has numberof books = $24 * 2 = 48$

So, they have number of books together = $24 + 48 = 72$ : Answer

Hope it will help :)

Is there an x intercept in the equation 60*1.15^x

Natali [406]

Answer:

Step-by-step explanation:

The equation $60*1.15^x$ is an exponential function. Exponential functions do not cross the x-axis unless they have been shifted down through subtraction in the function. All exponential functions have asymptotes that the function approaches but never crosses or touches. This function has an asymptote at the x-axis.
