Answer:

$\frac{4}{9}$

Step-by-step explanation:

To find this probability, we have to know:

How many numbers are there in between 5 and 8 inclusive?
How many total numbers are there?

We simply divide the first answer by the second one and get our probability.

So, the numbers are 5,6,7,8 ----- that is 4 numbers

How many numbers are there in total? That is:

0, 1, 2, 3, 4, 5, 6, 7, 8, or 9 ------- 9 numbers

Thus, the probability is 4/9

CaHeK987 [17]

The correct answer for this question is this one: "<span>147"</span>

Here's how to solve this problem.

Let <span>x = number of mystery books on the shelf </span>
<span>Let 3x = total number of books on the shelf </span>

<span>we are told that </span>
<span>x/5<10<x/4 </span>
<span>multiply by 20, </span>
<span>4x<200<5x </span>
<span>which means that </span>
<span>40<x<50 </span>
<span>So the number of mystery books can be any number between 41 and 49.
In other words, the possible total number of books could be three times the above numbers, 123, 126, 129,.... </span>
Choose the one that suits your answer choices.

Here are the following choices:
Which could be the number of books on the shelf?

Thirty percent of Irma’s Boutique’s sales came from leggings. They sold $390 worth of leggings last week. What were the total sa

RUDIKE [14]

Answer:

The total sales of Boutique last week = $1300

Step-by-step explanation:

Given that:

Percent of sales came from leggings = 30%

Worth of leggings sold = $390

Let,

x be the total sales in the week.

30% of x = 390

$\frac{30}{100}x=390$

0.3x = 390

Dividing both sides by 0.3

$\frac{0.3x}{0.3}=\frac{390}{0.3}\\x=1300$

Hence,

The total sales of Boutique last week = $1300
