Combine like terms in each expression 1. 1/4k+1/4m-2/3k+5/9m
2. -4b + 2w + (-4b) + 8w
3. 6- 5z + 8 - 4z + 1

5/12k = 29/36m

8b = 10w

9z = 15

Step-by-step explanation:

Combining the like terms in these sets of equations is quite easy and straightforward. All we do is carry the like terms to either of the side of the equation, and question is solved. As in below

1/4k + 1/4m - 2/3k + 5/9m =

1/4k - 2/3k + 1/4m + 5/9m = 0

-5/12k + 29/36m = 0

5/12k = 29/36m

-4b + 2w + (-4b) + 8w =

-4b - 4b + 2w + 8w = 0

-8b + 10w = 0

8b = 10w

6- 5z + 8 - 4z + 1 =

6 + 8 + 1 - 5z - 4z = 0

15 - 9z = 0

9z = 15

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

too many. (jk)

31 v bucks

step-by-step explanation:

since you bought 25 on friday and 6 on tuesday, you can just add them up.

25+6=31
