That's how i did it step by step. i'm fairly confident that i'm right, but if i'm not, i'm so sorry. have a good day! (:
First it has a sign second 3 can be divided by 18. lastly 18 is greater than 3n
Yes the expression has like terms. Because 2b and 5b both have the variable b we can add the two coefficient together without the changing the variable. So 2b+5b can become 7b
Hope this helps!<span />
The value of (x-y) is 16
Further explanation:
We have to use the given values to find the value
Given
We will use:
Simplifying by using: 
So,
As we know that x+y=4
Putting the value in equation
Dividing both sides by 4
The value of (x-y) is 16

Answer:
we say the number of samples is 4
Step-by-step explanation:
Given data
sample = 100
total sample conduct = 4 time
to find out
What is the number of samples
solution
we know that sample size for each month is 100
4 time sample taken January, march, June and September.
so that no of people sample is = 4 × 100 = 400
so that for number is sample is 400 /100
so we say the number of samples is 4
