Answer:
b. If n is not divisible by 2 or n is not divisible by 3, then n is not divisible by 6.
Step-by-step explanation:
Division by Six
A number is divisible by six if it is divisible by both 2 and 3.
Negation:
If the number is not divisible by either 2 or 3, it is not by 6. So the answer is given by option b.

Multiply both sides by 3

Simplify the numerators

Multiply both sides by 6

Simplify the numerator

Multiply both sides by x
12x - 18 = 15x Subtract 12x from both sides
-18 = 3x Divide both sides by 3
-6 = x Switch the sides to make it easier to read
x = -6
Check your answer by plugging -6 in for the x in the original problem:

Plug in -6 for x

Change

to

so all denominators are the same

Change

to

for easier work

Subtract the numerators (4 - (-1) )

=

So,
x = -6 .
The answer would be 17. to get this, i subtracted 7 from both sides, which will give you 0 and 17. 17 is 17inches/units from 0. kinda an easy way to do this :P
The second one. Do the math. .35 x 63 = 22.05
