Step-by-step explanation:
1 Subtract \frac{1}{3}
3
1
from both sides.
b-\frac{1}{3}=ab−

=a
2 Switch sides.
a=b-\frac{1}{3}a=b−

Answer:
the additive inverse of -5=0
the multiplicative inverse of -5=1
Answer: x = 1
3x + 4 = 7
subtract 4 from both sides
3x = 3
x = 3/3 = 1
Answer:
2 is the absolute mean deviation
Step-by-step explanation:
absolute mean deviation is
the average of the differences of the data from the average
8, 8, 4, 12
1. take the average
8+8+4+12=32 -> 32/4 = 8
2. subtract each number from this average
8 - 8 = 0
8 - 8 = 0
4 - 8 = 4 (there are no negative answers)
12 - 8 = 4
3. take the average of these subtractions
0+0+4+4=8 -> 8/4 = 2
4. answer: 2 is the absolute mean deviation
