Hello from MrBillDoesMath!
Answer:
n = 5
Discussion:
Let the original number be "n" Translating the problem statement to mathematical symbolism:
n + 4 = 19 - 2n => add 2n to both sides
n + 2n + 4 = 19 - 2n + 2n => combine like terms
3n + 4 = 19 => subtract 4 from both sides
3n = 19 -4 = 15 => divide both sides by 3
n = 15/3 =5
Check: Does 5 +4 = 19 - 2(5)? Does 9 = 9? Yes. so the value for n is confirmed correct.
Thank you,
MrB
Hey there!
Basically it wants you to add 3 and 8 from each other, what ever the answer to that part, you multiply the result by 9
Here this is what i meant
Or you could do this method too!
They both give you the result of 
So, I am assuming your expression would look like this: 
Good luck on your assignment and enjoy your day!

Answer: 0.512, 0.020, 0.012, 0.002
Step-by-step explanation:
To put these decimals in the order from greatest to least, we first need to make sure they all have the same place values.
0.012, 0.002, 0.020, 0.512
Now that they have the same place values, we can see which is bigger.
