Answer:
x = 8/13
Step-by-step explanation:
6 - 3x - 3/5(15x + 20) = 7(2x/7 - 2) - x
6 - 3x - 9x - 12 = 2x - 14 - x
6 - 12 + 14 = 2x - x + 3x + 9x
8 = 13x
x = 8/13

So, we have:
Using the attached graph, we have:
So, we have:
31. There are C(5, 2) = 10 ways to choose 2 colors from a group of 10 colors if you don't care about the order. (Here, we treat blue background with violet letters as being indistinguishable from violet background with blue letters.)
Only one of those 10 pairs is "B and V", so the probability is 1/10.
a) P(B and V) = 10%
32. The 12 inch dimension on the figure is 0 inches for the cross section. The remaining dimensions of the cross section are
c) 5 in. × 4 in.
_____
C(n, k) = n!/(k!·(n-k)!)
C(5, 2) = 5!/(2!·3!) = 5·4/(2·1) = 10
