Answer:
x=-22
Step-by-step explanation:
to get x by itself, subtract 12 from both sides: -22=x
Answer:
<h2><u><em>
9 mm</em></u></h2>
Step-by-step explanation:
A triangle has a height of 6mm and an area of 27mm2. What is the length of the base of the triangle?
----
To calculate the area of a triangle, multiply the height by the width (this is also known as the 'base') then divide by 2.
We use the inverse formula
base = 2A : height
2 * 27 : 6 = 9
------------------------
check
6 * 9 : 2 = 27
the answer is good
The formula for slope is the change in y over the change in x
m=slope
m=4-2/5-7
m=2/-2
m=-1
it has a slope of -1
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.
You have defined x to be the smaller of two consecutive integers. Then the larger will be (x+1). The given relation is
... (x) + 3(x+1) = -5 . . . . the smaller plus 3 times the larger is -5
... 4x + 3 = -5 . . . . . . . .simplify
... 4x = -8 . . . . . . . . . . subtract 3
... x = -2 . . . . . . . . . . . divide by the coefficient of x
The smaller of the two integers is -2.
