Answer: He should have used the mean to determine the average because the data sets are approximately symmetric.
Step-by-step explanation
The answer is
y= - x-9/3 I believe.
1- Subtract 9 from both sides.
-3y = x - 9
2- Divide both sides by -3
y = - x-9/3
9514 1404 393
Answer:
x = 27°
Step-by-step explanation:
The supplements of each angle are complementary:
(180 -6x) +(180 -4x) = 90 . . . . . . . . assumes x is in degrees
270 = 10x . . . . . . add 10x-90
27 = x . . . . . . . . . divide by 10
90,000 since you are rounding the whole number to ten thousand 90,000 is more closer than 80000. you have to round to the number it's asking so the rest of your answer after ten thousand should be left zero. therefore making the answer 90,000.
