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>

A segment with endpoints A(2,6) and C(5,9) is partitioned by a point B such that AB and BC form a 3:1 ratio. Find B​
Aneli [31]

Answer:

The coordinate of point B is (4, 8.25)

Step-by-step explanation:

Here, we want to find the coordinates of point B

To do this, we are to use the section internal division formula as follows;

(x,y) = (nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)

In this case;

(x1,y1) = (2,6)

(x2,y2) = (5,9)

(m,n) = (3,1)

Substituting these values into the section formula, we have;

(x,y) = (1(1) + 3(5))/(1 + 3) , (1(6) + 3(9))/3 + 1)

(x,y) = (16/4, 33/4)

(x,y) = (4,8.25)

Brilliant_brown [7]

Answer:

The best option is c

Step-by-step explanation:

The same textbooks contains a total of 848 pages . Which represent the total number of pages , y , of any number of the same textbooks , x.

The number of same text book = x

Each of this textbook contains a total of 848 pages .

The total number of pages can be computed as

y = 848x

for 4 same text book

y = 848 × 4 = 3392 pages

for 3 same text book

y = 848 × 3= 2544 pages

for 7 same text book

y = 848 × 7 = 5936 pages

for 8 same text book

y = 848 × 8 = 6784 pages

for 11 same text book

y = 848 × 11 = 9328 pages
