x-y=-10
2x+4y=22 Solving Systems by Substitution
Answer:
[1] x - y = -10
[2] 2x + 4y = 22
Step-by-step explanation:
// Solve equation [1] for the variable x
[1] x = y - 10
// Plug this in for variable x in equation [2]
[2] 2•(y -10) + 4y = 22
[2] 6y = 42
// Solve equation [2] for the variable y
[2] 6y = 42
[2] y = 7
// By now we know this much :
x = y-10
y = 7
// Use the y value to solve for x
x = (7)-10 = -3

A farm irrigation system waters a large field. Consider
the center of the field as the origin and the rest of the
field as a grid measured in yards. The first irrigation
unit is located at the point (-400, -200) and waters 500
yards in every direction. The second is located at (200,
300) and waters 400 yards in every direction. The
system of inequalities represents this scenario.
Crops watered by both systems will most likely grow
more quickly. Which location will receive the maximum
amount of water?

Jeff has 7 dimes and Trevor has 20 nickels. How much more money does Trevor have than Jeff?
Answer:
Trevor has 30 more cents than Jeff.
Step-by-step explanation:
Jeff:
1 dime = 10 cents.
So we do 10x7=70.
So Jeff has 70 cents.
Trevor:
1 nickel = 5 cents
So we do 20x5 = 100 cents which is the same thing as 1 dollar.
Then we do 100 cents - 70 cents which is 30 cents.
What fraction of all the 10-digit numbers with distinct digits have the property that the sum of every pair of neighboring digits is odd?
Answer:
1/126
Step-by-step explanation:
Answer attached, I hope this is the answer.
the sum of every pair of neighboring digits is odd must be odd number and even number in the neighbor. (different parity)
The fraction of all the 10-digit numbers with distinct digits that have the property that the sum of every pair of neighboring digits is odd is 1/126.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
We have two types of fractions.
Proper fraction and improper fraction.
A proper fraction is a fraction whose numerator is less than the denominator.
An improper fraction is a fraction where the numerator is greater than the denominator.
Example:
1/2, 1/3 is a fraction.
3/6, 99/999 is a fraction.
1/4 is a fraction.
We have,
For a 10-digit number to have the property that the sum of every pair of neighboring digits is odd, the digits must alternate between odd and even numbers.
Specifically, if the first digit is odd, then the second digit must be even, the third digit must be odd, the fourth digit must be even, and so on.
If the first digit is even, then the second digit must be odd, the third digit must be even, the fourth digit must be odd, and so on.
There are 5 odd digits and 5 even digits, so there are 5 choices for the first digit. After selecting the first digit, there are 5 choices for the second digit (it must be one of the other type), 4 choices for the third digit (it must be the opposite type of the second digit), 4 choices for the fourth digit (it must be the opposite type of the third digit), and so on.
Therefore, the number of 10-digit numbers with distinct digits that have the given property is:
5 x 5 x 4 x 4 x 3 x 3 x 2 x 2 x 1 x 1 = 5! x 4!
where the factorials arise from the number of choices for each digit.
The total number of 10-digit numbers with distinct digits is:
10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 10!
Therefore, the fraction of all the 10-digit numbers with distinct digits that have the given property is:
(5! x 4!) / 10! = (5! x 4!) / (10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1) = 1/126
Thus,
The fraction of all the 10-digit numbers with distinct digits that have the property that the sum of every pair of neighboring digits is odd is 1/126.

Saul decides to use the IQR to measure the spread of the data. Saul calculates the IQR of the data set to be 27
Saul asks Jasmine to check his work. Saul coples the data in numerical order from least to greatest for Jasmine.
25, 30, 50, 50, 50, 50, 56, n., 250
What is the value of n that will make the IQR of the data set equal to 27
Answer:
n = 78
Step-by-step explanation:
IQR is the interquartile range of the data set.
So Saul had already arranged the data in order, that is the first step when calculating the interquartile range.
25, 30, 50, 50, 50, 50, 56, n., 250
Next, is to find the median so we could easily separate the data into quartiles.
The median of the data 25, 30, 50, 50, 50, 50, 56, n., 250 = 50
Then, arrange the data into the first quartile and the third quartile
first quartile = 25, 30, 50, 50
third quartile = 50, 56, n., 250
first quartile median = 30 + 50 = 80/2 = 40
third quartile = 56 + n /2
The interquartile range formula is the first quartile subtracted from the third quartile:
IQR = Q3 – Q1.
Since 27 is the interquartile range, n=
27 = (56 + n /2) - 40
Use 2 to multiply through to eliminate the denominator
54 = (56 + n) - 80
n = 78
Question 1 Can you construct one, many, or no triangle(s) with side lengths of 3 inches, 4 inches, and 8 inches?
Answer: No triangles
Step-by-step explanation: The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Which is why 3,4, and 8 do not make a triangle, hope this helped!!
Are these ratios equivalent?
8 sneakers to 20 sandals
4 sneakers to 10 sandals
Answer:
yes
Step-by-step explanation:
For the first ratio we can simplifiy it by divide the two numbers by 4
8:4 = 2
20: 4 = 5
2 sneakers to 5 sandals
For the second ratio we can simplify it by dividing the two numbers by 2
4 : 2 = 2
10 : 2 = 5
2 sneakers to 5 sandals
we have found that the two ration are equivalent
The mean of 19 students is 126cm.
Another student joins the group and the mean becomes 128cm.
What is the height of the new student?
Answer: 166 cm
Step-by-step explanation:
x / 19 = 126
* 19 * 19
x = 2394
(2394 + y) / 20 = 128
* 20 * 20
2394 + y = 2560
- 2394 - 2394
y = 166

Find the mean of the integers: –12, –4, –11, –6, 4 (Find the sum and divide by how many values there are.)
Answer:
The appropriate answer is "-5.8". A further solution is explained below.
Step-by-step explanation:
The given integers series is:
[tex]-12,-4,-11,-6,4[/tex]
As we know,
⇒ [tex]Mean=\frac{Sum \ of \ All \ Data \ Points}{Number \ of \ Data \ points}[/tex]
On substituting the values, we get
