Marcy and troy disagreed about the answer to a problem. marcy said that the equation they were working on had more than one solution. if marcy is correct, on which of these equations could they have been working?
select one:
2x + 4 = 2(x + 2)
2x + 4 = 2(x + 3)
2x + 4 = 3x + 5
2x + 4 = 3x + 4

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to
