x−y=−5x
x−y=1/3
Answers
Solution:
Given:
x - y = -5xx - y = 1/3Substitute the value of "x - y" into equation 1.
x - y = -5x1/3 = -5xDivide -5 both sides.
1/3 ÷ -5 = -5x/-51/3 x 1/-5 = xx = 1/-15 = -1/15Substitute the value of x into equation 2.
x - y = 1/3-1/15 - y = 1/3-1/15 - y = 5/15-y = 5/15 + 1/15y = -6/15 = -2/5Putting the solutions in (x,y) form.
⇒ (x,y) ⇒ (-1/15, -2/5)Answer:
(x, y) = (-1/15, -2/5)
Step-by-step explanation:
You want to solve the system of equations by substitution:
x -y = -5xx -y = 1/3SubstitutionWe can use the second equation to substitute for (x-y) in the first equation:
1/3 = -5x
-1/15 = x . . . . . . . . divide by -5
Substituting this value into the second equation, we have ...
-1/15 -y = 1/3
-1/15 -1/3 = y = -6/15 = -2/5
The solution is (x, y) = (-1/15, -2/5).

Matthew's dad hired him to paint 6 wooden patio chairs for $125. It takes him 9 hours to paint all of the chairs. If it takes the same amount of time to paint each chair, what fraction of an hour does it take Matthew to paint one chair? Justify your thinking with a model.
Answers
Given:
Matthew's dad hired him to paint 6 wooden patio chairs for $125.
Time taken by him to paint all of the chairs = 9 hours.
It takes the same amount of time to paint each chair.
To find:
The fraction of an hour does it take Matthew to paint one chair
Solution:
Total time = 9 hours
Total number of chairs = 6
Now, time taken by Matthew to paint one chair is
[tex]\dfrac{\text{Total time}}{\text{Total number of chairs}}=\dfrac{9}{6}[/tex]
[tex]\dfrac{\text{Total time}}{\text{Total number of chairs}}=\dfrac{3}{2}[/tex]
Therefore, Mattew takes [tex]\dfrac{3}{2}[/tex] of an hour to paint one chair.
Thinking with a model: On dividing the total time by total number of chairs we get time taken by Mattew (in hours) to paint one chair. So, the result represents the fraction of an hour taken by Matthew to paint one chair.

Step-by-step explanation:
Given the following :
Dimension of fabric = 48 by 168
What is the length of the largest square pieces into which shelly and mickelle can cut the fabric?
To obtain this, find the greatest common factor of both numbers in the dimension:
Using the table format:
___ _48 ____168
_ 2__24 ____ 84
_2__12 _____42
_2__6 _____ 21
_3__3______ 7
Since there is no number which can divide both anymore
The greatest common factor = (2 * 2 * 2 * 3) = 24

How much should Michael deposit from each paycheck if the paycheck is bi-weekly? a. $80 b. $74 c. $160 d. $37 Please select the best answer from the choices provided A B C D.
Answers
There is $74 Michael deposit from each paycheck if the payback os bi-weekly, the correct option is B.
What is the insurance?The insurer and the insured get a legal contract for the insurance, which is called the insurance policy.
Given
Car insurance premium in a first half year = $958
Car insurance premium in the second half year = $958
Total Car insurance premium in year = 2 × $958 = $ 1916
Nature of paid premium is bi-weekly = in 2 weeks
There are total 52 weeks in a year.
The total number of bi-week = 26
Total deposited amount per bi-weekly is;
= $ 1916 ÷ 26 =$ 73.69 ≈ $ 74
Hence, there is $74 Michael deposit from each paycheck if the payback os bi-weekly.

What is the x-coordinate of the midpoint of line segment AB with points A(62, 5) and B(-46, -13).
Answers
Answer: 5
Step-by-step explanation:
The x-coordinate of the midpoint of the segment is the average of the x-coordinates of the two endpoints.
Therefore, the x-coordinate of the midpoint of AB is the average of the x-coordinate of A and the x-coordinate of B.
We are given that the x-coordinate of A is 62 and of B is -42.
The average of 62 and -42 = (62-42)/2 = 10/2 = 5

The required solution to the given inequality is x > 16, as shown in the graph.
What is inequality?In mathematics, an inequality is a statement that two values or expressions are not equal. An inequality uses one of the comparison symbols: "<" (less than), ">" (greater than), "≤" (less than or equal to), "≥" (greater than or equal to), or "≠" (not equal to). For example, "x + 3 < 10" is an inequality that states that the value of x plus 3 is less than 10.
Here,
As mentioned in the question,
To graph, the solution of the inequality (x+8) > 2 (2.0 + 10).
Simplifying the given inequality:
(x+8) > 2 (2.0 + 10)
x+ 8 > 2(12)
x > 24 - 8
x > 16
Thus, the required solution to the given inequality is x > 16.

Answers
Step-by-step explanation:
Let g represent the number of gloves purchased and h represent the number of hats purchased.
The gloves cost $12 and a hat costs $8
We need to write an inequality that represents this situation.
Cost of gloves = $12g
Cost of hats = $8h
No more than $56 means [tex]\le 56[/tex].
We can write the inequality as follows :
[tex]12g+8h\le 56[/tex]

Answer:
It is C
Step-by-step explanation:
So 3.75 is the rate of change, when she goes to get a drink it changes it subtracts the amount which Mia has which is $50. so we could put y=-3.75x+50 as the equation because for the number of drink she buys multiply by how much she cost will be the money she has to spend, so by subtracting by 50 her gift card will give how much money she will have in her gift card
Hope this helps
Answer: y= -3.75x + 50
Each drink costs Mia $3.75. Since spending money causes her to lose money, this value will be negative. Therefore, we will put -3.75x in the beginning of the equation.
Mia has $50 on a gift card. Since this amount is positive (she has a positive amount of money) and remains constant (the amount on the gift card won't change) we will put +50 at the end of the equation.
