I believe the anwser is c.
To find the answer all you have to do is subtract 10 from 526.
So, 526 - 10 = 516
Hope this helped :)
This is just combining like terms.....
6n2 - 5n2 + 7n2
n2 + 7n2
=8n2
Answer:
C; Substitution property
Step-by-step explanation:
Here, we want to find the justification that justifies the written equation;
If PQ + RS = PS
and RS = XY
then PQ + XY = PS
What we simply did is to substitute RS for XY in the second equation;
The correct answer is Substitution property
It can be fully referred to as the substitution property of equality.
What it simply means in a nut shell is that since XY and RS are equal, then in any addition or arithmetic equation, we can make a substitution of XY for RS since they are equal to each other
