First Answer:
x = 12
First Step-by-step explanation:
12 + x = -3(4 - x)
12 + x = -12 + 3x
- x - x
—————————
12 = -12 + 2x
+ 12 + 12
—————————
24 = 2x
24/2 = 2x/2
12 = x
Second Answer:
No solution
Second Step-by-step explanation:
2(x - 1/2) = 8 + 2x
2x - 1 = 8 + 2x
+1 +1
—————————
2x = 9 + 2x
- 2x - 2x
—————————
0 = 9

Answer:
333/364 or 0.915
Step-by-step explanation:
Red marbles = 5
Blue marble = 3
Green marble = 6
Total number of marbles in the bag = 5 + 3 6 = 14
1. The first draw, we have 5 red marbles out of 14 marbles = 5 / 14
Now we have 13 marbles left of which 4 are red.
2. Second draw, we have 4 red marbles and a total of 13 marbles = 4 / 13
3. Third draw, we have 12 marbles left and 3 are red. = 3 / 12 = 1 / 4
Probability of drawing all the red marbles = (5 / 14) * (4 / 13) * (1 / 4) = 333 / 364 = 0.9148

Sue travels by bus or walks when she visits the shops. The probability that she catches the bus to the shops is 0.4. The probability she catches the bus from the shops is 0.7. Show the probability that Sue walks at one way is 0.72
Answer:
(Proved)
Step-by-step explanation:
Sue travels by bus or walks when she visits the shops.
Let the event that she catches the bus to the shop=A
Let the event that she catches the bus from the shop=B
P(A)=0.4
P(B)=0.7
Both A and B are independent events.
Therefore,Probability that she catches the bus to and from the shop:
P(A∩B) = 0.4 X 0.7= 0.28
Probability Sue walks at least one way 
Hence, the probability that Sue walks at least one way is 0.72.
