What does n equal in: -6(n+1) = 42 . need quickly. you!

It is -7.83 because you distribute the -6 to the n and the 1 inside the parentheses which makes you get -6n-5=42. Since 5 is negative you add it to -5 and the 42 on the other side of the equation which turns out to -6n=47. You then divide -6 on both sides of the equation. -6n divided by -6 cancels out so 47 divided by -6 equals -7.83333333 which rounds to -7.8

4 matches

Step-by-step explanation:

The probability of winning is 65%, the probability of a draw is 15%. So the probability of lossing a match is

100% - 65% - 15% = 20%

Now that you know the probability of lossing, you have to multiply it by the number of matches

P(lossing) = 20 * 20%

P(lossing) = 20 * (20/100)

P(lossing) = 20 * 0.2

P(lossing) = 4
