Jesse saves $112.50 per week, Nick saves $51.25 per week, and Owen saves $56.25 per week.
Explanation:
To find out how much money each person saves per week, we need to set up a system of equations. Let's start by assigning variables to the amounts saved by each person. Let 'J' represent the amount saved by Jesse, 'N' represent the amount saved by Nick, and 'O' represent the amount saved by Owen.
2O = J (Jesse saves twice as much as Owen)
N + 5 = O (Owen saves $5 more than Nick)
J + N + O = 220 (The total amount saved by all three is $220)
Now, we can substitute the values in the equations to find the amounts saved by each person.
From the first equation, J = 2O. Substituting this value in the third equation gives us: 2O + N + O = 220. Simplifying, we get 3O + N = 220.
From the second equation, N + 5 = O. Rearranging, we get N = O - 5. Substituting this value in the third equation gives us: 3O + (O - 5) = 220. Simplifying, we get 4O = 225. Solving for O, we find that Owen saves $56.25 per week.
Substituting this value in the second equation, we find that Nick saves $51.25 per week. Finally, substituting the values in the first equation, we find that Jesse saves $112.50 per week.

Step-by-step explanation:
Find the values of x and y that make k || j and
m || n.
x =
y =
Answer:
x= 80
y= 130
Step-by-step explanation:
The correct values of x and y that make k || j and m || n are x = 130 and y = 130.
To find the values of x and y, we need to use the fact that if two lines are parallel, their corresponding angles are equal.
Given that k is parallel to j, we have:
x = 50 (corresponding angles)
Since m is parallel to n, we have:
y + 80 = 210 (corresponding angles)
Solving for y:
y = 210 - 80
y = 130
Now, we have the value of x as 50 and the value of y as 130. However, we also know that the angles x and y are supplementary because they form a straight line. Therefore, their sum must be 180 degrees.
x + y = 180
50 + y = 180
y = 180 - 50
y = 130
This confirms that y is indeed 130 degrees. Since x and y are supplementary and both equal to 130 degrees, we have a contradiction because the sum of x and y should be 180 degrees.
To resolve this contradiction, we must re-evaluate our initial assumption that x = 50 degrees. Since x and y are supplementary, and we have correctly determined that y = 130 degrees, we must have:
x + y = 180
x + 130 = 180
x = 180 - 130
x = 50
This is incorrect because we initially assumed x = 50 degrees based on corresponding angles, but we did not consider that the angle adjacent to x on line k is not given and could be different from the corresponding angle of 50 degrees on line j.
To correct this, we should consider the angle adjacent to x on line k, which must sum up with x to 180 degrees because of the straight line. Let's call this angle x'. Since k is parallel to j, x' corresponds to the angle of 130 degrees on line j. Therefore, we have:
x' + x = 180
130 + x = 180
x = 180 - 130
x = 50
Now, considering that x and y are supplementary:
x + y = 180
50 + y = 180
y = 180 - 50
y = 130
Thus, we have x = 50 degrees and y = 130 degrees, which are indeed the values that make k || j and m || n. However, since x and y are supplementary, they must both be 130 degrees to satisfy the conditions of the problem.
Therefore, the correct values are x = 130 degrees and y = 130 degrees.

Based on the information, the correct option is 4. Reflexive Property of congruent to; SSS
What is congruence?The reflexive property of congruence states that any geometric figure is congruent to itself. In other words, any shape or object is congruent to itself.
For example, if we have a triangle ABC, we can say that triangle ABC is congruent to triangle ABC. This is because all the corresponding sides and angles of the two triangles are equal, and they represent the same geometric figure.
NO and ON are the same line. They are congruent by the reflexive property (a line segment is a reflection of itself). Shape MNO and shape PON are congruent by side-side-side since:

M is the midpoint of CF for the points C(1, 2) and F(7, 10). Find MF.
To calculate the length of MF, find the midpoint M of CF using the midpoint formula, then use the distance formula to determine the length of MF, which is 5.0 cm.
Explanation:To find the length of the segment MF, we must first determine the coordinates of the midpoint M of the segment CF. Since C has coordinates (1, 2) and F has coordinates (7, 10), we use the midpoint formula which is ( (x1 + x2)/2, (y1 + y2)/2 ). Calculating this for C and F gives us the coordinates of M as:
x-coordinate of M = (1 + 7)/2 = 4y-coordinate of M = (2 + 10)/2 = 6Therefore, M has coordinates (4, 6). Now, to find the distance MF, we use the distance formula between points M and F:
MF = √[(x2 - x1)² + (y2 - y1)²] where (x1, y1) are the coordinates of M and (x2, y2) are the coordinates of F.
Replacing with the known values:
MF = √[(7 - 4)² + (10 - 6)²]
MF = √[3² + 4²] = √[9 + 16] = √25 = 5.0 cm
Thus, the length of the segment MF is 5.0 cm.

Answer: D. {12, 13, 14, 15, 16, 17, 18}
Step-by-step explanation:
The union of two sets A and B is the set of elements which are in A, in B, or in both A and B, without repetition.
In this case, the union of the sets G and H will be the set of elements in G= {12, 14, 16, 18} and then the set of elements in H= {13, 15, 17, 18}, excluding those that already were in G, which in this case is the number 18.
Then:
G ∪ H={12, 13, 14, 15, 16, 17, 18}

Simplify the expression. 3y3 – 2y[4y – y(y – 3)] – [2y(y + 1) – 3y(y2 –1)] =
Answer:
Step-by-steThe first step for solving this expression is to distribute -y through the parenthesis.
3y³ - 2y × (4y - y² + 3y) - (2y × (y + 1) - 3y × (y² - 1))
Distribute 2y through the parenthesis.
3y³ - 2y × (4y - y² + 3y) - (2y² + 2y - 3y × (y² - 1))
Now distribute -3y through the parenthesis.
3y³ - 2y × (4y - y² + 3y) - (2y² + 2y - 3y³ + 3y)
Collect the like terms in the first set of the parenthesis.
3y³ - 2y × (7y - y²) - (2y² + 2y - 3y³ + 3y)
Collect the like terms in the second set of the parenthesis.
3y³ - 2y × (7y - y²) - (2y² + 5y - 3y³)
Distribute -2y through the parenthesis.
3y³ - 14y² + 2y³ - (2y² + 5y - 3y³)
Remember that when there is a "-" sign in front of the parenthesis,, you must change the sign of each term in the parenthesis. This will change the expression to the following:
3y³ - 14y² + 2y³ - 2y² - 5y + 3y³
Collect the like terms with an exponent of 3.
8y³ - 14y² - 2y² - 5y
Lastly,, collect like terms that have an exponent of 2.
8y³ - 16y² - 5y
Since we cannot simplify the expression any further,, the correct answer is going to be 8y³ - 16y² - 5y.

Suppose you have 19 black socks and 19 green socks in the dryer. 4. without looking, how many socks would you need to pull out of the dryer to be sure you get a black pair?
You would need to pull out 21 socks from the dryer to ensure you have a black pair since you might initially pull out all 19 green socks before getting to the black ones.
To determine how many socks one would need to pull out of the dryer to be sure to get a pair of black socks when you have 19 black socks and 19 green socks, consider the worst-case scenario. In the worst case, you pull out all 19 green socks one by one. Since you have not yet pulled out a single black sock, the 20th sock you pull out has to be black, because there are no more green socks left. However, to ensure you have a pair of black socks, you will need to pull out one more sock. So the answer is that you need to pull out 21 socks to be certain of having a pair of black socks.

A fracture in the left femoral region that is 5 centimeters proximal to the patellar region and 30 centimeters distal to the coxal region will be __________.
A fracture in the left femoral region that is 5 centimeters proximal to the patellar region and 30 centimeters distal to the coxal region will be located in the midshaft of the femur.
The femur is the long bone in the thigh, and it has distinct regions:
Coxal Region (Hip Region):
This refers to the upper end of the femur, which articulates with the hip bone (coxal bone).
A fracture occurring here would typically be near the hip joint.
Patellar Region (Knee Region):
This refers to the lower end of the femur, where it articulates with the patella (knee cap).
A fracture here would typically involve the knee joint.
Midshaft of the Femur:
This is the region between the coxal and patellar regions.
A fracture that is 5 centimeters proximal (closer to the hip) to the patellar region and 30 centimeters distal (away from the hip) to the coxal region would be located in the midshaft of the femur.
Fractures in the midshaft of the femur can vary in severity, and treatment may depend on factors such as the type of fracture (e.g., simple, comminuted), the extent of displacement, and the patient's overall health.
These fractures are often serious and may require surgical intervention, such as the placement of pins, screws, or a metal rod to stabilize the bone and promote proper healing.
Rehabilitation and physical therapy are also crucial for recovery and restoring function.

Write an equation of the line passing through point P(−8, 0) that is perpendicular to the line 3x−5y = 6
To find the equation of a line perpendicular to another line, we need to find the negative reciprocal of the slope. Substituting the values into the point-slope form, we can find the equation of the perpendicular line.
Explanation:To find the equation of a line that is perpendicular to another line, we need to find the negative reciprocal of the slope of the given line. The given line has the equation 3x - 5y = 6, so its slope is 3/5. The negative reciprocal of 3/5 is -5/3, so the slope of the line perpendicular to the given line is -5/3.
Since we know a point on the perpendicular line is P(-8, 0), we can use the point-slope form of a line to find the equation. The point-slope form is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line. Substituting -8 for x1, 0 for y1, and -5/3 for m, we get y - 0 = -5/3(x - (-8)).
Simplifying the equation gives y = -5/3x - 40/3, which is the equation of the line passing through point P(-8, 0) and perpendicular to the line 3x - 5y = 6.
