Answer:
14x+6z
Step-by-step explanation:
distribute 2 into (4x-3z) and 3 into (2x+4z)
8x-6z+6x+12z
combine like terms
8x+6x=14x
12z-6z=6z
14x+6z

Answer:
(a) Each piece is “berry or cherry” with probability p = 1/2. The proba-
bility of only berry or cherry pieces is p
12 = 1/4096.
Step-by-step explanation:
(b) Each piece is “not cherry” with probability 3/4. The probability all 12
pieces are “not pink” is (3/4)12 = 0.0317.
(c) For i = 1, 2, . . . , 6, let Ci denote the event that all 12 pieces are flavor i.
Since each piece is flavor i with probability 1/4, P[Ci
] = (1/4)12. Since
Ci and Cj are mutually exclusive,
P[F1] = P[C1 ∪ C2 ∪ · · · ∪ C4] = X
4
i=1
P[Ci
] = 4 P[C1] = (1/4)11

Step-by-step explanation:
![\frac{7}{3} (x + \frac{9}{28} ) = 20 \\ \frac{7x}{3} + \frac{3}{4} = 20 \\ \frac{7x \times 4}{3 \times 4} + \frac{3 \times 3}{4 \times 3} = 20 \\ \frac{28x + 9}{12} = 20 \\ 28x + 9 = 20 \times 12 \\ 28x + 9 = 240 \\ 28x = 240 - 9 \\ 28x = 231 \\ x = \frac{231}{28} \\ x = 28\frac{7}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7B3%7D%20%28x%20%2B%20%20%5Cfrac%7B9%7D%7B28%7D%20%29%20%3D%2020%20%5C%5C%20%20%5Cfrac%7B7x%7D%7B3%7D%20%20%2B%20%20%5Cfrac%7B3%7D%7B4%7D%20%20%3D%2020%20%5C%5C%20%20%5Cfrac%7B7x%20%5Ctimes%204%7D%7B3%20%5Ctimes%204%7D%20%20%2B%20%20%5Cfrac%7B3%20%5Ctimes%203%7D%7B4%20%5Ctimes%203%7D%20%20%3D%2020%20%5C%5C%20%20%5Cfrac%7B28x%20%2B%209%7D%7B12%7D%20%20%3D%2020%20%5C%5C%2028x%20%2B%209%20%3D%2020%20%5Ctimes%2012%20%5C%5C%2028x%20%2B%209%20%3D%20240%20%5C%5C%2028x%20%3D%20240%20-%209%20%5C%5C%2028x%20%3D%20231%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B231%7D%7B28%7D%20%20%5C%5C%20x%20%3D%2028%5Cfrac%7B7%7D%7B8%7D%20)
