Answer:
Unit rate of people per book = 2.5
Step by step explanation:
Given:
Number of peoples = 
Number of books = 
Their ratios = 
We have to find the unit rate of people per book.
To find out the unit rate of people per book we have to divide the total number of peoples by the total number of books.
Or
For this we will follow the unitary method:
For book there are persons.
For 
book there will be 
persons.
So,
The numeric value =
= 
There are 2.5 people per book and that it also the unit rate of people per book.
Answer:
They can be arranged in 6 ways.
Step-by-step explanation:
4×5
5×4
10×2
2×10
20×1
1×20
Change in y: -2, goes down 2
Change in x: 5, goes right 5
slope: change in y/ change is x
which is -2/5, and that's B
The correct question is
<span>The product of two consecutive positive integers is
11 more than their sum. find the integers.
Let
x-------> the first </span>positive integer
x+1-----> the second consecutive positive integer
we know that
x*(x+1)=11+(x+(x+1))----> x²+x=11+(2x+1)----> x²+x=2x+12
x²-x-12=0
using a graph tool------> to resolve the second order equation
see the attached figure
the solution is
x=4
therefore
the numbers are
x=4
x+1=5
the answer isthe numbers are 4 and 5
