If solving a system of linear equations by elimination or substitution I get that 2=3, it means (check all that apply)
If the system of equations is 2 linear equations in 2 variables, there is infinity number of solutions
If the system of equations is 3 linear equations in 3 variables, there is infinity number of solutions
If the system of equations is 2 linear equations in 2 variables, the system has no solutions
If the system of equations is 3 linear equations in 3 variables, the system has no solutions
Answer:
If I get 2=3 in solving the system, it means the following:
If the system of equations is 2 linear equations in 2 variables, the system has no solutions If the system of equations is 3 linear equations in 3 variables, the system has no solutionsStep-by-step explanation:
The solution of linear system of equations implies that a point has to be found that holds true on all equations involved.
The system may consist of two equations involving two unknowns or may consist of three equation with three unknowns.
When a system of equation has no solution, the variables are removed in solving the equations and we get an equation or values in the form.
constant = constant
So,
If I get 2=3 in solving the system, it means the following:
If the system of equations is 2 linear equations in 2 variables, the system has no solutions If the system of equations is 3 linear equations in 3 variables, the system has no solutionsThe term GLOBAL ETHIC refers to a set of common moral values and ethical standards which are shared by the different faiths and cultures on Earth.
These common moral values and ethical standards constitute a humane ethic, or, the ethic of humanity. In view of the process of globalization this ethic of humanity has been termed by the famous Roman Catholic theologian and philosopher Professor Hans Küng as the “GLOBAL ETHIC”.
Although the concept of a GLOBAL ETHIC was at first introduced by Professor Hans Küng in 1989 it is, in his own words, “not a new invention but only a new discovery” of common principles which are as old as humankind.
There can be no doubt that a globalizing world with its tremendous social, ecological and moral problems needs a globalization of moral values and ethical standards, in short: a GLOBAL ETHIC, in order to survive as a place where our grandchildren and great-grandchildren can live a decent life.

Answer:
First one: A 4 in 12 chance
Step-by-step explanation:
Answer:
1/3
Step-by-step explanation:
The coin was flipped 12 times. Out of the 12, Tashi tagye was gotten 4 times. That will be 4/12. Reducing to the lowest tem will get 1/3
For Anthony’s birthday, his mother is making cupcakes for his 12 friends at his daycare. The recipe calls for 3 1/3 cups of flour. This recipe makes 2 1/2 dozen cupcakes. Anthony’s mother has only 1 cup of flour. Is there enough flour for each of his friends to get a cupcake
Answer:
No, there is no enough flour for each of his friends to get a cupcake
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ This recipe makes 2[tex]\frac{1}{2}[/tex] dozen cupcakes
∵ Each dozen contain 12 cupcakes
∴ The number of cupcakes can the recipe make = 2[tex]\frac{1}{2}[/tex] × 12
∴ The number of cupcakes can the recipe make = 30 cupcakes
∵ The recipe calls for 3[tex]\frac{1}{3}[/tex] cups of flour
→ That means 3[tex]\frac{1}{3}[/tex] cups of flour can make 30 cupcakes
∴ 3[tex]\frac{1}{3}[/tex] cups of flour makes 30 cupcakes
∵ Anthony’s mother has only 1 cup of flour
→ By using the ratio method
→ flour : cupcake
→ 3[tex]\frac{1}{3}[/tex] : 30
→ 1 : x
→ By using cross multiplication
∵ 3[tex]\frac{1}{3}[/tex] × x = 1 × 30
∴ 3[tex]\frac{1}{3}[/tex] x = 30
→ Divide both sides by 3[tex]\frac{1}{3}[/tex]
∴ x = 9
∵ x represents the number of cupcakes
∴ Anthony’s mother can make 9 cupcakes with 1 cup of flour
∵ Anthony has 12 friends at his daycare
∵ The number of the cupcakes = 9
∴ The number of cupcakes is not enough for each of his friends to
get a cupcake

At a little-known vacation spot, taxi fares are a bargain. A 14 Mile Taxi ride takes 16 minutes and costs 11.20 you want to find the cost for a 49 mile taxi ride
Answer:
the unit price needed to calculate is $0.8 per mile
Step-by-step explanation:
Here is the complete question:
At a little-known vacation spot, taxi fares are a bargain. A 14 Mile Taxi ride takes 16 minutes and costs $11.20 you want to find the cost for a 49 mile taxi ride . What unit price do you need?
Step-by-step explanation:
To determine the unit price needed to calculate the cost for a 49 mile taxi ride, we will determine the cost of the ride per mile. To do this, let the cost per mile be $x
If it cost $11.20 for a 14 mile ride
Then, it will cost $x for a 1 mile ride
∴ x = (1 × 11.20) / 14 = 0.8
x = 0.8
The taxi ride costs $0.8 per mile.
Hence, the unit price needed to calculate is $0.8 per mile.
If desired,
To find the cost for a 49 mile taxi ride, multiply the distance traveled by the unit price,
Distance = 49 mile
Unit price = $0.8 per mile
∴ Cost for a 49 mile taxi ride = 49 × $0.8
Cost for a 49 mile taxi ride = $39.2
Hence, the cost for a 49 mile taxi ride is $39.2

Which option correctly shows how this formula can be rearranged to isolate x^2?
Options in picture.
Answer:
A
Step-by-step explanation:
We have:
[tex]\displaystyle m=\frac{x_1-x_2}{y_1-y_2}[/tex]
And we want to isolate x₂.
So, let’s first remove the denominator by multiplying both sides by it:
[tex]\displaystyle m(y_1-y_2)=\frac{x_1-x_2}{y_1-y_2}(y_1-y_2)[/tex]
The right side will cancel. This will leave:
[tex]\displaystyle m(y_1-y_2)=x_1-x_2[/tex]
Now, we can subtract x₁ from both sides. So:
[tex]\displaystyle m(y_1-y_2)-x_1=-x_2[/tex]
Finally, we will multiply both sides by -1. So:
[tex]\displaystyle x_2=-m(y_1-y_2)+x_1[/tex]
Hence, our answer is A.

Eli and his children went into a movie theater and will buy candies and pretzels. Each candy costs $3.50 and each pretzel costs $3.25. Eli has a total of $30 to spend on candies and pretzels. Write an inequality that would represent the possible values for the number of candies purchased, cc, and the number of pretzels purchased, p.p.
Answer: He spent $7.25 dollars.
Step-by-step explanation:
$3.50 + 3.25 = 7.25Inequality shows a relationship between two numbers or two expressions.
The inequality that would represent the possible values for the number of candies purchased c and the number of pretzels purchased p is
3.50c + 3.25p ≤ 30
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
We have,
Cost of candy = $3.50
Cost of a pretzel = $3.25
Total amount to spend = $30
Let the number of candies = c
Let the number of pretzels = p
The inequality to spend on possible numbers of candies and pretzels:
3.50c + 3.25p ≤ 30
Thus,
The inequality that would represent the possible values for the number of candies purchased c and the number of pretzels purchased p is
3.50c + 3.25p ≤ 30

Compare data set A and data set B.
Set A: mean = 79.6, standard deviation = 9.8
Set B: mean = 79.6, standard deviation = 2.3
Answer:
Set A: mean = 79.6, standard deviation = 9.8
Step-by-step explanation:
Set A has a larger spread of data.
If Set A: mean = 79.6, standard deviation = 9.8 and Set B: mean = 79.6, standard deviation = 2.3 then set A has larger spread of data compared to set A.
What is Statistics?Statistics is the study and manipulation of data, including ways to gather, review, analyze, and draw conclusions from data.
Given,
Set A:
mean = 79.6,
standard deviation = 9.8
Set B:
mean = 79.6,
standard deviation = 2.3
As we compare both set A and set B the mean of set A and set B are same whereas set A has more standard deviation than set B.
As Standard deviation is an important measure of spread or dispersion.
if the standard deviation is small, then this tells us that the results are close to the mean, whereas if the standard deviation is large, then the results are more spread out.
Set A has a larger spread of data.
Hence Set A has larger spread of data compared to set A.

Given:
Henry can type 3500 words in 70 minutes.
Colin can type 1500 in 30 minutes.
Brian can type 2200 words in 40 minutes.
To find:
The person who types at the fastest rate of words per minute.
Solution:
We know that,
[tex]\text{Rate of words per minute}=\dfrac{\text{Number of words}}{\text{Number of minutes}}[/tex]
Using this formula, we get
[tex]\text{Henry's rate of words per minute}=\dfrac{3500}{70}=50[/tex]
[tex]\text{Colin's rate of words per minute}=\dfrac{1500}{30}=50[/tex]
[tex]\text{Brian's rate of words per minute}=\dfrac{2200}{40}=55[/tex]
Since 55>50, therefore Brian's types at the fastest rate of words per minute.
