C and D both have variables because u don’t know what the x stands for
( I hope this helped)
-2n + 1.8 = 3.2
Subtract 1.8 from both sides
-2n = 1.4
Divide both sides by -2
n = 1.4/-2 = 0.7/-1 = -0.7
n = -0.7
Check your work:
-2(-0.7) + 1.8 = 3.2
1.4 + 1.8 = 3.2
3.2 = 3.2
The answer is B. -0.7

Answer:y=2/3x
Step-by-step explanation:
If your number is quite large, like 3 digit or higher than that, then calculate the sum of their digits, if they will be divisible by 3, then the number is divisible, otherwise not.
For example. - "11055"
Here, sum of digits = 1 + 1 + 0 + 5 + 5 = 12
As 12/3 = 4 (Divisible)
In short, This number would be divisible.
Hope this helps!
