Answer:
x = 12
Step-by-step explanation:
3(x - 1) - 2x = 9 remove the brackets using the distributive property
3x - 3 - 2x = 9 Collect 3x and -2x (Collect like terms)
3x - 2x - 3 = 9 Use the reverse of the distributive property to get x
x(3 - 2) - 3 = 9 Do what is inside the brackets
x - 3 = 9 Add 3 to both sides (additive inverse)
x - 3 + 3 = 9+3 Combine like terms on the left
x = 12
Answer: Our required probability is 0.18.
Step-by-step explanation:
Since we have given that
Probability that husband is on the internet = 10% = 0.10
Probability that husband is not on the internet = 1-0.10 = 0.9
Probability that wife is on internet given that husband is on internet = 40% = 0.40
Probability that wife is on internet given that husband is not on internet = 20% = 0.20
Probability that wife is on internet is given by
So, Probability that the husband is also on internet given that wife is on internet is given by

Hence, our required probability is 0.18.
I am mostly sure it's b. Good luck! :3

Answer: 11
Step-by-step explanation:
Based on te question in the picture (which is different from what you wrote)
x^2 - 3x + 1
-2^2 - 3(-2) + 1
4 + 6 + 1 = 11
