Can you please help me with this? I don't really understand it.
Q: 5(x+10)+x
A. 6x + 15
B. 5x + 15
C. 6x + 50
D. 4x - 50
I tried to work out the problem and I came out with A. Am I right? Thanks.
No.
5(x+10)+x
5x + 50 + x = 6x + 50
Oh I see it now. I get why I got it wrong.
Could you also help me with another math problem? Every time I do the problem my answer isn't coming out right.
Sure. Please post the problem.
Okay thank you.
-4n + 7 + 2n = 1
A. 1
B. 3
C. -3
D. 4
-4n + 7 + 2n = 1
-2n + 7 = 1
-2n - -6
n = 3
Oh okay, I was doing it completely wrong. Thank you so much Ms. Sue.
You're very welcome.
Of course! Let me explain how to solve this equation step by step.
The given equation is: 5(x+10) + x.
To simplify this expression, we need to apply the distributive property, which states that when you have a number (or variable) outside parentheses multiplying an expression inside the parentheses, you need to distribute that number to each term within the parentheses.
So, let's distribute the 5 to the terms inside the parentheses: 5 * x + 5 * 10 + x.
This simplifies to: 5x + 50 + x.
Now, we can combine like terms by adding the x terms together: 5x + x = 6x.
Finally, we have: 6x + 50.
Therefore, the correct answer is C. 6x + 50.
