Answer:
corresponding
Step-by-step explanation:
I think it is 1/3 because rise over run and so you go up 1 and over 3
Answer:
you put two of the equations together and then the last one there you just automatically added on
Step-by-step explanation:
4x-7y=-28
25xy
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 greatest common factor is 1
