For the following set of baseball runs scored at each game, identify:
• the mean
• the median
• the mode
• the range
• the interquartile range
12, 16, 16, 21, 22, 25, 28
which measure of center would the baseball team want to use to show what a great team they are--the mean or the median?

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
