1)   2x=5x+18

   3x=−18

     x=−6

2)   (a + b) + (b + c) + (a + c) = 29 + 45 + 44

    a + b + b + c + a + c = 118

    2a + 2b + 2c = 118

     2(a + b + c) = 118

       a + b + c = 59

3)  x = -5

Math! Need help will give brainliest if CORRECT
SOVA2 [1]

Hey there! I'm happy to help!

So we want to see which of these have the greatest value. Since these are all negative numbers, we want the one that is closest to zero.

So, we know that -1000 is going to furthest from 0. -10 will be further than -8 since it is a larger negative number, so it will be more negative than -8.

-1/2 is just barely negative, so it is going to be closer to -0 than -8, so the correct answer is C. -1/2.

Have a wonderful day and keep on learning! :D

Aidan has put 21 hours of work. To simplify it, Harry worked 7 hours and Aidan worked 7 x 3 times which equates to 21 hours.
