It doesn't give me that as an option.I have another question. Write an situation that can be represented by 6n+4. Is this right? Brooke has n number of coins that are worth $6 each.If she also has 4 dollar bills in her purse,how much does she have in total?

Ms.Sue
I think it is 3G+30. I can't figure out the situation problem.I'm good at subtraction situations but I keep drawing a blank on the addition.

Thank you so much!

Ms Sue
Thank you.I didn't know * was multiplication.So, would I explain she is not correct because?I don't know how to answer the why part.I knew they would be different I just don't understand why.

Ms Sue
I'm just making sure that you knew I meant the x was multiplication.I don't understand why the a is not represented with a number.I was thinking that I would have to find what a equals.Thank you for helping me.

This is wrong. You were suppose to use the distributive property. Here, let me show you: -3(2+3x)+x-5 = -6+-9x+ x-5 Then, you combine like-terms: -6-5= -11 and then -9x+x= -8x Thus, your answer should be -11-8x. Hope I helped you a little bit.

How I got the answer: 8+5+10+3= 26 Since there were 5 sets of numbers I did 35-26 (because 7 times 5 is 35) which is 9. So when you add them up, it would be : 8+5+10+3+9= 35 35/5 = 7 Therefore, the answer is 9. Hope this helps!
