Answer:
Step-by-step explanation:
We have to organize the given polynomials from the least to greatest based on their degrees.
A). x + 2xyz
Here xyz = 
Power of x is = 1
Power of y = 1
and power of z = 1
So degree of (x + xyz) will be degree of the highest degree term = 1 + 1 + 1 = 3
B). 9x³y²
Degree of this term = power of x + power of y = 3 + 2 = 5
C). 18x²+ 5ab - 6y
Degree of the polynomial = Highest degree of the variable x = 2
D). 
Degree of highest degree term 
= 4
So sequence of the polynomials based on their degrees will be
C - A - D - B [From lowest to highest]

Answer:
Option A. The cost of one pack of ballpoint pens is $3 and the cost of one pack of gel pens is $7.
Step-by-step explanation:
Let
x -----> the cost of one pack of ballpoint pens
y -----> the cost of one pack of gel pens
we know that
60x+25y=355 -----> equation A
120x+30y=570 -----> equation B
Solve the system of equations by graphing
Remember that the solution of the system is the intersection point both graphs
The solution is the point (3,7)
see the attached figure
therefore
The cost of one pack of ballpoint pens is $3
The cost of one pack of gel pens is $7
The answer is 1.7 there you go.
