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>

Here are the following choices:
Which could be the number of books on the shelf?
A. 120 B 140 c 147 D 150
The answer is:
11) The midpoint is (0,3)
12) The midpoint is (1,3)
Plug 35 in for z. Multiply 4 and 35 to get 140 then divide by 7 to get 20

Step-by-step explanation:
1 cm = 25000cm = 1/4 km. 9*1/4=9/4=2 1/4= 2.25
First u get both sides to match in varibles .........so factor in the 2 .....2*4m =8m... and 2*-5=-10 ... which gives u 8m-10
now u have 3m-10=8m-10
next get the same varibles on the same side
3m-10=8m-10
-3m
-10=5m-10
same thing for other side
-10=5m-10
+10
0=5m
➗
both sides by 5
should get m=0
