Directions: solve each of the following equations.

a. combine like terms

b. then isolate the variable if necessary

c. follow rules for signed numbers

11. 76x + 23x = 33

12. 140r - 8r - 4r = 216

13. 98c - 99c = 1

14. 104mn + (-84mn) = 36

15. 118j - 234j = 234

(i appreciate all your ) u

Step-by-step explanation:

11. 76x + 23x = 33

    99x = 33

   x = 33/99 which reduces to 3

12. 140r - 8r - 4r = 216

    128r = 216

   r = 216/128 which reduces to 27/16

13. 98c - 99c = 1

-1c = 1

c = -1/1

c = -1

14. 104mn + (-84mn) = 36

    104mn - 84mn = 36

   20mn = 36

   mn = 36/20 which reduces to 9/5I am not sure about this one...I was not                sure if u were looking for m or n..so I didn't separate them. But if ur looking for m, it is m = 9/5n...and if ur looking for n, it is n = 9/5m

15. 118j - 234j = 234

   - 116j = 234

    j = -234/116 reduces to - 117/58

72 is the answer to this problem

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
