Step-by-step explanation:
mean of cheese = 99+8+10/3 = 117/3 = 39
mean of butter = 41+16+0/3 = 57/3 = 19
mean of non fat dairy milk = 255+8+15/3 = 278/3 = 92.6~93
median of cheese 8, 10, 99 median is 10
median of butter 0, 16, 41 median is 16
nonfat dairy milk 8, 15, 255 median is 15
range of cheese 99-10 = 88
range of butter 41-16 = 25
range of nonfat dairy milk = 255-8 = 247

Answer:
y = 5x/7 + 10/-7
Step-by-step explanation:
subtract 5x from both side and you should get -7y = -5x + 10
divide negative 7 into both side -7/-7 = -5x/-7 + 10/-7
and the answer is y = 5x/7 + 10/-7
