Answer:

1) 9c-3c= -8-4

6c=-12

c=-12/6

c=-2

2) 3×5x-3×2-6x=3×3x+3×2

15x-6-6x=9x+6

15x-6x-8x=6-6

15x-14x=0

x=0

3)-x+7x=24

6x=24

x=24/6

x=4

4) -2r-1/2×-2=-2

-2r+1=-2

-2r=-2-1

-2r=-3

r=-3/-2

r=3/2

timama [110]

Answer:

24

Step-by-step explanation:

For this problem, you need to find the greatest common factor because you need to divide all of the materials equally into identical sets.

If you factor out the numbers 48, 72, and 120, (same # of blue, green, and yellow crayons) you'll get the GCF of 24.

48 - 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

72 - 1, 2, 3, 4, 18, 6, 8, 9, 12, 24, 36, 72

120 - 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

The greatest common factor in all of these lists is 24.

Therefore, the largest number of identical sets is 24.

(2 blue crayons, 2 green crayons, 2 yellow crayons, 3 red crayons, 5 colored pictures)
