Bobbie: x comic books
Kenny: 9 more comic books than Bobbie: x + 9
Together: 95 comic books
To write the equation that could be used to find the number of comic books they each have, we have to put it together:
x + (x + 9) = 95
x + x + 9 = 95
2 * x = 95 - 9
2 * x = 86 /2
x = 86 / 2
x = 43
Result: Bobbie has 43 comic books, Kenny has 52 comic books (43 + 9).
The error is that -2 times -5 is 10 not -10. Then carry on from there because that error meant the rest is wrong as well.

Question 6: y =
x + 100
Question 7: y = -10x + 45
Answer:
D
Step-by-step explanation:
The mean of a standard normal distribution is always = 0 with the standard deviation being equal to. Therefore a standard normal distribution is a normal distribution described with a mean of 0 and standard deviation of 1. Since a standard normal distribution is centered at the middle with equal distribution to both the left and right of the distribution. The centre point is 0, which is the mean and the standard deviation is 1 to either side of the distribution.
