Answer: the x or the input of a function
Step-by-step explanation:
2
n
−
7
=
19
Explanation:
Well first we should look at the part that says "twice a number"
This number can be anything so let's assign a variable to it
Let
n
=
a number
And we also see at the end "twice a number equals 19"
So we get
2
n
=
19
Then we see that "Seven less than"
2
n
all equals
19
So we get
2
n
−
7
=
19
Now if you would want to solve this equation you first add
7
to both sides and we get
2
n
=
26
Then we divide both side by
2
So
n
=
13
The answer should be number two
The absolute value is the magnitude of a number. In other words, how far from 0 it is. All the does is make the number positive, but since 11/4 is already positive, the answer is just 11/4.
To measure the area of a triangle, you need to know the height and the base. Some figures can have different methods to finding the area, but in the end the answer will be the same.
