your friend evaluates the expression when m = 10. is your friend correct? Explain your reasoning.

3m - 6 = 3(10) - 6
= 3(4)
=12

PLS HELP ASAP!

Answers

Answer:

yes

Step-by-step explanation:

3 * 10 (m) = 30 so 30 - 6 = 24. 3(10) - 6 is basically the same thing just written different, so it equals 24 too. 3(4) just means 3 times 4 ,which equals 13. Hope that made sense lol

yes ,

3•10 = 30 - 6 = 24

now when you do 3(4) you get 12 and then subtract the 12 from the 24 and you get 12

percentage = 12000 / 3000 = 4

2.1      Solve  :    -8n-5 = 0  

Add  5  to both sides of the equation :  

                     -8n = 5

Multiply both sides of the equation by (-1) :  8n = -5

Divide both sides of the equation by 8:
