Answer:

There are 21 books in a table if the number of books is 3/4th of the cost of each book then what is the cost of each book.

Solution :

Let c represents the cost of each book,

Also, the number of books = 21

According to the question,

3/4th of the cost of each book = total number of books

\implies \frac{3}{4}c = 21

Which is the required equation.

Answer: Real world problem is "A student have c toffee he distribute \frac{3}{4}th part of those toffees to his friends. He gave total 21 toffees to his friend".

Explanation:

Let a student have c number of toffees in his bag.

It is given that he distribute \frac{3}{4}th part of those toffees to his friends.

The \frac{3}{4}th part of c toffees is,

\frac{3c}{4}

The total number of distributed toffees is 21.

\frac{3c}{4}=21

It is the same as given equation.

If we change the equation in words it means the \frac{3}{4}th part of a number c is 21.

two different subtraction problems that use only odd numbers for numerators and each have different of 3/4.​
Irina18 [472]

Answer:

  • 3/2 - 3/4
  • 5/3 - 11/12
  • 5/4 - 1/2
  • 7/5 - 13/20
  • 5/6 - 1/2
  • 9/7 - 15/28
  • 9/8 - 3/8
  • 9/10 - 3/20
  • 9/11 - 3/44

Step-by-step explanation:

We did a systematic search for subtraction problems of this type, eliminating ones that are too trivial, such as 1/1 - 1/4 and equivalents of those with integers added, such as 3/1 - 9/4. Even so, there are an infinite number of possibilities. some of the ones involving larger numbers in the range we looked at include ...

  • 41/45 - 29/180
  • 41/49 - 17/196
  • 41/53 - 5/212

___

A reasonable approach to doing this by hand seems to be to choose a denominator for the minuend, then a denominator 4 times that value for the subtrahend. Express 3/4 using the latter denominator, and find two numbers that differ by that numerator, one of which is divisible by 4, but not by 8.

<u>Example</u>: Choose 13 as the minuend denominator. Then 52 is the subtrahend denominator, and the difference you need to create is 39/52. The smallest odd number we can add to 39 to make it divisible by 4 but not 8 is 5. So, we can use (39+5)/52 and 5/52 as our numbers that differ by 3/4. In reduced form, that subtraction is ...

  11/13 - 5/52

Note that if you choose an even denominator, then the exact procedure will vary depending on what power of 2 is a factor of the denominator.

What is this data an example of?<br><br> *serious answers only*
Ray Of Light [21]
<h3>Answer: A) linear function</h3>

Each time x goes up by 2, y decreases by 4

This indicates we have a linear function. The slope in this case would be

m = rise/run = (change in y)/(change in x) = -4/2 = -2

The y intercept can be found by following these steps

y = mx+b

0 = -2(5)+b

0 = -10+b

10 = b

b = 10

Therefore, the equation of this line is y = -2x+10. Plug in something like x = 1 and it should lead to y = 8. The same applies for any other column of x,y values.
