Question

Which of the following expressions could be simplified further?

2x + 3m + 7n + 4z − 5p

6x − 7m + 9x

4x + 3m − 5z + 8a

2x + 3m − 5y + 4z

Answer 1

Evaluate: 8 − (−7)

Answer 2

i got 56

Answer 3

and for the other i got answer 3

Answer 4

I really believe its 2 because you can just add the 6x and the 9x and it wont and the result will be the same.

Answer 5

and a negative times a positive is a negative.

Answer 6

so it should be -1

Answer 7

lets help eachother here......... so doesn't (-7) mean that your suppose to multiply the 7 and the 8? if so then because your multiplier is a negative your result will be a negative. they dont subtract eachother, please, tell me if I am wrong

Answer 8

being honest am not sure because i dont have a good grade in algebra that why am trying to get help

Answer 9

yeah, I'm here to learn to :D

Answer 10

hmm, give me some time...

Answer 11

me too

Answer 12

got it! you see your only suppose to multiply if theres no insignia next to the parenthesis, so since there is an insignia (8-) the only thing your suppose todo is just subtract, so 8- -7=1!

Answer 13

thanks i got one more if u can

Answer 14

A concession stand charges $2.00 per soda and $0.50 per candy bar. Write an expression for the amount of money you would need to buy x sodas and y candy bars

Answer 15

and for your first question I am right-o that you can simplify 6x − 7m + 9x and turn it into
15x -7x

Answer 16

Hit me! :D

Answer 17

this is what i got
20/sodas,.5 candy bars
x=soda y=candy bars
so the expression will be 20x+.5y

Answer 18

tell me if am right

Answer 19

Answer 30

a way to express the number of candy bars and sodas sold is this:
let x (sodas) = 200 and y (candy bars) = .50
and let m = money
Now,a n equation to buy 1 soda and 2 candy bars is

2x+1y=m tada!
