X equals 38. That means, angle R is 38, angle P is 69, and angle Q is 73.

You get x=38 by doing x+35+x+2x-7 = 180

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

$0.1\times 0.4+0.9\times 0.2\\\\=0.04+0.18\\\\=0.22$

So, Probability that the husband is also on internet given that wife is on internet is given by

$\dfrac{P(\text{wife and husband both on internet)}}{P(wife\ on \ internet)}\\\\=\dfrac{0.4\times 0.1}{0.22}\\\\=\dfrac{0.04}{0.22}\\\\=0.18$

Hence, our required probability is 0.18.
