Answer:
12
Step-by-step explanation:
Given:
-8
+20°
Solution:
-8+20 = 12
Therefore the answer is 12
2x - 1 = 9 - 14x
16x - 1= 9
16x = 10
x = 10/16
x= 5/8 is the answer
Not sure about the first one,
The second one is 1/9.
The total number of fish available in the tank is (18 + 22) = 40. The probability for 1 goldfish to be taken out would be 18/40. Now, after drawing the first fish, the probability to get another goldfish would be 17/39. And the probability to draw 2 goldfish would be the product of both probabilities. P = (18/40)(17/39) = 51/260 So,the answer is B.
