I believe the correct answer choice is 1 because the only factors of 8 are 2 and 4 which dont factor in to 75 or 21
8-4/5f=-14-2f
Multiply both sides by 5
40-4f=-70-10f
Move variable to left and change signs
-4f+10f=-70-40
Combine like terms
6x=-70-40
6f=-110
Divide both sides by 6
F=-55/3
Answer:
4 2/7
Step-by-step explanation:
It is convenient to let a spreadsheet or graphing calculator do the tedious math for you. (See the attachment.)
_____
The sum of the numbers is 56, so their average is 56/7 = 8. Then the absolute deviations from average are ...
... 8, 5, 2, 1, 3, 5, 6
and the total of these is 30. The mean absolute deviation is this sum divided by the number of numbers, 7, so is ...
... 30/7 = 4 2/7

"Absolute" here refers to the absolute value function, which drops the sign of a negative number. The absolute deviation of the data value 0 is ...
... |0 - 8| = |-8| = 8
For 3, it is ...
... |3 - 8| = |-5| = 5

Answer:
Answer:
if you add −5, the inequality is 13 > -12
if you add 2.7, the inequality is 20.7 > -4.3
if you add 7, the inequality is 25 > 0
