16. For the the equation 4x+8 9x+3.
Explain the steps that were used to solve the equation below
4X + 8 9X+3
4x + 5 = 9x
5 = 5x
1 = X
4X + 8 9X+3 (this is the equation, nothing to explain in this step)
4x + 5 = 9x (you combine or subtract the like terms, 8 - 3 = 5)
5 = 5x (you do 9x - 4x = 5x, subtracting the like terms)
1 = X (your answer after dividing 5 from both sides)
An item is purchased for a wholesale price of $48 and will be sold at a 55 percent markup. Which expression should be used to find the amount of the markup?
48 dollars (0.55)
48 dollars (55)
48 dollars (0.55) + 48 dollars
48 dollars (55) = 48 dollars
Answer:
The answer is 48(0.55) x 48
Step-by-step explanation:
wholesale $48 and sold at 55% which is the same as 0.55 then multiply wholesale by percent

Step-by-step explanation:
The length of an American flag is 1.8 times its width. What is the
width of the flag?
length=10
Answer:
5.56 or put [tex](5 \frac{5}{9})[/tex]
Step-by-step explanation:
length = 1.8* width
if the length is 10 , we solve like this :
10 = 1.8* width
10/1.8 = width
width = 5.555.... [tex](5 \frac{5}{9})[/tex]
to 3 sf
width = 5.56
Parallel line geometry
==========================================================
Explanation:
See the diagram below. I've extended one of the rays to form a full line. This is shown in red. The alternate interior angles 60 and x are congruent due to the parallel lines, so x = 60.
We can then find angle y
x+y+20 = 180 ... angles of a triangle add to 180
60+y+20 = 180
y+80 = 180
y = 180-80
y = 100
Use this to find z
y+z = 180
100+z = 180
z = 180-100
z = 80
Or you could use the remote interior angle theorem
x+20 = z
60+20 = z
80 = z
z = 80

two fourth-degree polynomials are multiplied together. what is the degree of the product?
Answer:
The product of a fourth degree polynomial and a third degree polynomial is a 7th degree polynomial (just add the two degrees). Why is this the case? Remember, when you multiply variables with common bases, you add the exponents. Since the degree of a polynomial is just the largest exponent, you're really just adding the degrees when you multiply
How would you write 9^4 as an equivalent expression using a base of 3
Answer:

x + 5y +3z = 4
4y – z=3
6x – 2y + 4z = 0
Answer:
x = [tex]\frac{1}{4}[/tex]
y = [tex]\frac{3}{4}[/tex]
z = 0
Step-by-step explanation:
You first need to solve for a variable, it won't be as easy as x = 3, you are looking to replace a variable with another equation.
For example, the second equation, 4y-z=3, I can either solve for y or z. It won't be a numerical value but it will get you a step closer.
4y-z=3
4y=z+3
y = [tex]\frac{z}{4} +\frac{3}{4}[/tex]
Then you are able to use substitution to negate one of the variables and solve for the other two variables. I won't type that but I think you get the idea.
A dozen donuts cost 6.00. How much sould 3/4 of a dozen cost at the same rate
Answer: Should cost 4.50
Step-by-step explanation:
Because a full thing is 6 dollars, if you divide 6 by 4 you get 1.5 causing each 1/4 to be 1.5 dollars. 1.5X 3 is 4.5
Which is defined using the undefined terms point and line?
A) angle
B) circle
C) parallel lines
D) ray
Answer:
i would say circle cause there no evan lines angles or points in it
Step-by-step explanation:
The object which is defined using undefined terms of points and lines is option D)
D) Ray
Reason for electing the above option is as follows;
Undefined terms are terms that are not required to be given formal definition in them selves and they include the terms set, plane, line, and point
A point is a dimensionless marker of position and it is indicated in geometry by a capital letter. In geometry, a point is the most elementary entity
A line is an infinitely long and straight geometric object that is defined and named by any two points located on it
A ray is a subset of a line that extends long straight infinitely in one direction, and has a starting point
Therefore, the geometrical object defined by a point and a line is a ray and the correct option is option D)
