perimeter: 16, calculate
the value of x when the length
of the rectangle is 3x and the
hieght is x
Step-by-step explanation:
Perimeter = 16
length = 3x
height = x
P = 2L + 2H
16 = 2(3x) + 2(x)
16 = 8x
hence:
x = 2.

Part 1:
Graph the following system of equations. What is the solution set?
2x + y = 3
x = 2y - 1
Part 2:
Solve the following system of equations by substitution. What is the solution set?
y = -2x + 3
x - 2y = - 1
Part 3:
Compare the systems of equations and their solutions in Parts 1 and 2. How are they similar? How are they different?
Complete your work in the space provided or upload a file that can display math symbols if your work requires it. Include the graph of the linear system of equations and the process followed in order to solve the system by substitution.
Answer:
Part 1:
The solution set of the system of equations is x = 1, y = 1
Part 2:
The solution set is x = 1, y = 1
Part 3:
The similarity of the system of equations in Parts 1 and 2 is that they have the same solution set
The difference of the system of equations in Parts 1 and 2 is that they are arranged differently
Step-by-step explanation:
Part 1:
The system of equation is given as follows;
2·x + y = 3...(1)
x = 2·y - 1...(2)
The above system of equations can be written in terms of the variable, y, as follows;
For equation (1), we have;
y = 3 - 2·x
For equation (2), we have;
y = (x + 1)/2
From the attached graph created with Microsoft Excel, we have;
The solution set (the point of intersection) of the system of equations is x = 1, y = 1
To accurately find the common solution, we have;
(x + 1)/2 = 3 - 2·x
x + 1 = 2·(3 - 2·x) = 6 - 4·x
x + 1 = 6 - 4·x
x + 4·x = 6 - 1
5·x = 5
x = 5/5 = 1
x = 1
Therefore, y = 3 - 2·x = 3 - 2× 1 = 1, at the common solution
Part 2:
y = -2x + 3
x - 2y = -1
∴ x = 2y -1
y = -2(2y -1) + 3
y = -4y + 2 + 3
5y = 5
y = 1
x = 2y - 1 = 2 - 1 = 1
x = 1
The solution set is x = 1, y = 1
Part 3
The system of equations are similar in terms of their solution
The system of equations are different in terms of their arrangement

Step-by-step explanation:
The * sign is a way to show multiplication so that the "x" variable isn't mistaken for you to multiply or vice versa.
-3 * -6 = 18 because a negative number times a negative number has the sum of a positive number.

How may solutions does -3(x-2)=6-3x have
Answer:
Every real number is a solution.
Step-by-step explanation:
−3 (x − 2) = 6 − 3x
(−3) (x) + (−3) (−2) = 6 + −3x
−3x + 6 = 6 + −3x
−3x + 6 = −3x + 6
−3x + 6 + 3x = −3x + 6 + 3x
6 = 6

There are 8employees on The Game Shop's sales team. Last month, they sold a total of g games. One of the sales team members, Chris, sold 17 fewer games than what the team averaged per employee. How many games did Chris sell? Write your answer as an expression.
Answer:
(g/8) - 17
Step-by-step explanation:
Given that:
Number of employees = 8
Employees sold a total of g games
Chris sale = 17 fewer than team Average
Number of games Chris sold :
Team average :
Total sales made / number of employees
Team average = g/ 8
Number of games sold by Chris:

A triangle has sides of lengths 3.2 cm, 4.8 cm and 3.6 cm. Find the ratio of the lengths of the sides to one another
Answer:3/2
Step-by-step explanation:
i just had this on a test a triangle always equals this
The ratio of the lengths of the sides to one another is 0.8:1.2:0.9.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given that, a triangle has sides of lengths 3.2 cm, 4.8 cm and 3.6 cm.
The ratio of the lengths is 3.2:4.8:3.6
= 1.6:2.4:1.8
= 0.8:1.2:0.9
Therefore, the ratio of the lengths of the sides to one another is 0.8:1.2:0.9.

Keeping car tires inflated is essential to safe driving. For one type of car tire, the tire pressure in pounds per square inch (psi) is assumed to be approximately Normal with a mean of 35 psi and a standard deviation of 2 psi. A tire is labeled as underinflated if its pressure is 32 psi or below. What percentage of tires are underinflated?
a. 2.28%
b. 6.68%
c. 93.32%
d. 97.72%
Answer:
B 6.68
Step-by-step explanation:
The solution is, 30.854% is the percentage of tires are underinflated.
What is Z-score?In statistics, the standard score is the number of standard deviations by which the value of a raw score is above or below the mean value of what is being observed or measured. Raw scores above the mean have positive standard scores, while those below the mean have negative standard scores.
here, we have,
First, we find the z-score corresponding to the value given
z-score = (x - mean)/SD
Z-score = (36-35)/2 = 1/2 = 0.5
we find the Probability of (x > 0.5)
we use the standard normal distribution table for this
P( x > 0.5) = 0.30854
This has a percentage 30.854%.

Jada gets a quarters from a change machine at an arcade. She receives 4 quarters for every
dollar bill, d, that she puts into the machine.
What variable is dependent and independent between The number of dollor bills which is d and the number of quarters which is q??
Answer:
The dollar bills d are the independent variable while the number of quarters q are the dependent variable
Step-by-step explanation:
Here, we want to state the variable that is dependent and the one that is independent
from the question, she has to put in dollars to get the quarters
so the number of quarters she gets is dependent on the number of dollars put into the machine
Thus, we can conclude that;
The dollar bills are the independent variable while the number of quarters q are the dependent variable
Independent variables are those who are not dependent on other variables. In contrast, their exists dependent variables whose value depends on some other variable(s)' value(s).
For given case, the number of dollar bills 'd' is independent variable with respect to variable 'q'.
The number of quarters 'q' is dependent variable.
What are independent variables?Independent variables are those who are not dependent on other variables for their evaluation.
What are dependent variables?Those variables whose value is decided by the values of other variables. This shows that the variable in consideration is dependent on other variables for its values, thus called dependent variable.
Which of 'd' or 'q' is dependent and independent?If you see it carefully, you'll see that the quarters received from the change machine is depending on how much dollar bills you're feeding to the machine.
Thus, the value of 'q' is dependent on the value of d.
But since d takes its value independent of q (it exists before q exists and doesn't need q to get its values), thus, d is not dependent on q or is independent variable with respect to q(i said "with respect to q" since d might be dependent on some other variable which we do not know right know)
Thus:
The variable 'q' is dependent variable (depends on d)
The variable 'd' is independent variable with respect to 'q.
