<u>Answer:</u>

The answer is c = $\frac{d+ab}{a}$

<u>Solution:</u>

When a sum of two numbers is multiplied by a number, the number can be distributed to the addends separately, then adding the products together will produce the same result as multiplying sum by the number. This property is called distributive property of multiplication.

To find the value of, a(c-b)=d

On applying the distributive property of multiplication which is $[a\times(b+c)=a\times b+a\times c]$

Here we get,

$a\times(c-b)=a\times c-a\times b$

So the equation will be,

$a\times c-a\times b=d$

$ac-ab=d$

$ac=d+ab$

$c=\frac{d+ab}{a} or \frac{d}a+\frac{ab}{a}$

A visitor makes a list of 11 sights he’d like to see. He is determined to visit at least 8 of these. How many possible choices d

Cerrena [4.2K]

Using the combination formula, it is found that he has 232 choices.

The order in which the sights are seen is not important, hence the <em>combination formula </em>is used to solve this question.

<h3>What is the combination formula?</h3>

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this problem, the choices are 8, 9, 10 or 11 sights from a set of 11, hence:

$T = C_{11,8} + C_{11,9} + C_{11,10} + C_{11,11} = \frac{11!}{3!8!} + \frac{11!}{2!9!} + \frac{11!}{10!1!} + \frac{11!}{0!11!} = 232$

He has 232 choices.

What percent of 32 is 48?<br><br> A.67<br> B.46<br> C.33<br> D.none of above

elena55 [62]

Just by giving the numbers an analisys, we are able to find the answer, specially because we have options to choose from.

32 is a big part of 48. It's more than half, which would be 24 and would correspond to 50%. Therefore, nor 46 nor 33 can be answers, because 32 is more than the half of 48, so the answer is A.

Hope it helped,
