Daniela made her error on step 3 because it says:
"Find the ratio of the differences of the means compared to the mean absolute deviation.
She didn't find the difference between the today and last week means. She just put the mean as a whole.
Answer:
-31
Step-by-step explanation:
g(x) = -3x - 1
g(10) = -3(10) - 1
g(10) = -30 - 1
g(10) = -31
(2x + 3) + (x+1) + (3x-10) = 180
6x - 6 = 180
6x = 186
x= 31
(5x+7)(2x−3) is the answer
