5.
the steps below show the incomplete solution to find the value of x for the equation 6x – 2x – 5 = –6 + 21:
step 1: 6x – 2x – 5 = –6 + 21
step 2: 6x – 2x – 5 = 15
step 3: 4x – 5 = 15which of these is most likely the next step? (4 points)
4x = 10
4x = 3
4x = 45
4x = 20
6. asher solved the equation below:
4x = 64
4x – 4 = 64 – 4
x = 60
is asher's solution correct? if the solution is incorrect, explain why it is incorrect and show the correct steps to solve the equation. (5 points)

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
