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

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

other answer is correct. i had used the radius of the radius somehow. a website:
