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?

20 if f(x) = 4x + 5, what is the value of f(-3)?<br> A-2<br> B-7<br> C 17<br> 04
Juliette [100K]

Answer:

B. -7

Step-by-step explanation:

f(x) = 4x + 5

To find the value of f(-3), replace all the x's in f(x) with -3.

f(x) = 4x + 5

f(-3) = 4(-3) + 5

f(-3) = -12 + 5

f(-3) = -7.

This makes your answer B, -7.
