Consider the sequence of steps to solve the equation: 2(x - 4) + 6x = 9x - 10 Given 2/x - 4) + 6x = 9x – 10 Step 1 2x - 8 + 6x = 9x - 10 Step 22x + 6x - 8 = 9x - 10 Step 33 8x - 8 = 9x – 10 Step 4 = 8x - 8x - 8 = 9x – 8x – 10 Step 50 - 8 = x - 10 Step 6-8 = x - 10 Step 7 -8 + 10 = x - 10 + 10 Step 8 3 2 = x + 0 Step 9 = 2 = x Which step in solving this equation is justified by combining Like Terms

Now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.

One number is 4 less than 3 times a second number. if 3 more than two times the first number is decreased by 2 times the second number, the result is 11. use the substitution method. what is the first number?
