Answer:
k - 3
Step-by-step explanation:
In this expression, only 8k and 7k can be subtracted. This is because they have the same variable, meaning they are "like terms".
8k - 7k - 3 = 1k - 3

Answer:
2/5, 7/15, 8/15, 3/5, 2/3
Step-by-step explanation:
If these fractions are expressed with a common denominator, that would be 3×5 = 15. Then the given fractions are 1/3 = 5/15, and 4/5 = 12/15. The numerators 5 and 12 differ by 7, so we can easily choose 5 fractions in that range:
6/15 = 2/5
7/15
8/15
9/15 = 3/5
10/15 = 2/3

<em>Alternate solutions</em>
There is no requirement for the fractions to be written any particular way or with any particular spacing. The limits in decimal are 1/3 = 0.3333...(repeating) and 4/5 = 0.8. We could choose the decimal fractions ...
0.34, 0.40, 0.50, 0.60, 0.70
or
0.41, 0.52, 0.63, 0.74, 0.79
Answer:
1/3
Step-by-step explanation:
A direct variation has the form y=kx
k is the constant of proportionality
y = 1/3x
The constant of proportionality is 1/3
