Is correct because 3+0 is 3 and 4+2=6 so no BTW the anwser is 63
First, you need to use the distributive property and distribute the 2 inside the parentheses.
2(x + 1) + 3x = 17
2(x) + 2(1) + 3x = 17
2x + 2 + 3x = 17 -Combine like terms
2x + 3x + 2 = 17
5x + 2 = 17 -Subtract 2 from both sides of the equation.
5x + 2 - 2 = 17 - 2
5x = 15 -Finally, divide each side by 5 to find your answer
5x/5 = 15/5
x = 3
Hope this helps you!
Answer: c) 0.75
Step-by-step explanation:
Given : The probability of choosing a black marble is P(Black)= 0.36.
The probability of choosing a black and then a white marble is P( Black and white) = 0.27.
Then by conditional probability ,
The probability of the second marble being white if the first marble chosen is black = ![P(\text{white }|\text{Black})=\dfrac{\text{P( Black and white)}}{\text{P(Black}}](https://tex.z-dn.net/?f=P%28%5Ctext%7Bwhite%20%7D%7C%5Ctext%7BBlack%7D%29%3D%5Cdfrac%7B%5Ctext%7BP%28%20Black%20and%20white%29%7D%7D%7B%5Ctext%7BP%28Black%7D%7D)
![=\dfrac{0.27}{0.36}=\dfrac{27}{36}=0.75](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B0.27%7D%7B0.36%7D%3D%5Cdfrac%7B27%7D%7B36%7D%3D0.75)
Therefore , the probability of the second marble being white if the first marble chosen is black = 0.75
