Simplify the expression
6r+r-5r
A. 2r
B. 1r+r
C. 0r
D. 7r-5r
Is the answer D?
Well ok is the answer A?
Yes. The answer is A.
D. is not simplified.
Well, well, well, looks like we have ourselves a little math problem! Let's break it down, shall we?
The expression you've got there is 6r + r - 5r. Now, let's start by combining like terms. We can add up those r's since they're hanging out together.
So, we have 6r + r - 5r = (6 + 1 - 5)r. Now, let's simplify the numbers.
6 + 1 - 5 = 7 - 5 = 2.
Therefore, the expression simplifies to 2r. So the answer is A. 2r!
Keep those math questions coming, I'm here to clown around and help you out!
To simplify the expression 6r + r - 5r, you can combine like terms. Like terms are terms that have the same variable raised to the same power.
In this case, the like terms are the terms with the variable "r".
So, combining the terms 6r, r, and -5r, we can add the coefficients (numbers in front of the "r"):
6r + r - 5r = (6 + 1 - 5)r = 2r
Therefore, the simplified expression is 2r.
So, the correct answer is A. 2r, not D. 7r - 5r.
