Answer:
k = -4
Step-by-step explanation:
-4k + 2(5k − 6) = −3k – 48
Distribute on the left side.
-4k + 10k - 12 = -3k - 48
Combine like terms on the left side.
6k - 12 = -3k - 48
Add 3k to both sides.
9k - 12 = -48
Add 12 to both sides.
9k = -36
Divide both sides by 9.
k = -4
On a number line, -5 is to the left of 0.
Remember, on a number line, positive numbers (including fractions, decimals and surds) are to the right of 0:
----------------------------------------------------------------------->
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
Negative numbers (including rational and irrational numbers) are to the left of 0:
<-----------------------------------------------------------------
-8 -7 -6 -5 -4 -3 -2 -1 0
Hope it helps! Enjoy your day!

Answer:
511
Step-by-step explanation:
Each tube can be included in the mix, or not. There are 2^9 = 512 possible subsets of a set of 9 objects, including the complete set and the empty set. The empty set will not make a color, so there are ...
2^9 - 1 = 511 distinct color groupings that can be made
__
The assumption in the above answer is that no tube color can be made by any combination of other tube colors.* We also assume that the choice of tubes is what makes a "color grouping", and that the colors within that grouping made by using different ratios of paint quantities are not counted separately.
