∠FED and ∠DEW are complementary because it is a sum of 90 degrees.
By the law of addition of complementary angles, m∠FED + m∠DEW = 90°
m∠FED + m∠DEW = m∠FEW by the Angle addition postulate.
By the substitution property of equality, m∠FEW = 90°.
The ∠FEW is a right angle by the definition of right angles.
How to Interpret Complementary Angles?Complementary Angles defined as angles that sum up to 90 degrees.
Now, we are given that;
∠FED and ∠DEW are complementary.
We want to prove that ∠FEW is a right angle. Thus;
∠FED and ∠DEW are complementary because it is a sum of 90 degrees.
By the law of addition of complementary angles, we can say that;
m∠FED + m∠DEW = 90°
Also,
m∠FED + m∠DEW = m∠FEW by the Angle addition postulate.
By the substitution property of equality, m∠FEW = 90°.
The ∠FEW is a right angle by the definition of right angles.

Explain part A and B pls?
Answer:
MK= 12.5
AngleJNK=117°
AngleJNM=63°
Step-by-step explanation:
Part A:
MN = 3x + 1
JL = 2x + 9
JL and MK are the diagonals
MN = 1/2 of MK
MK =2(3x +1)
MK = 6x + 2
Therefore, JL = MK
2x + 9 = 6x +2
Collect like terms
2x-6x = 2 - 9
-4x = - 7
x = 1.75
Substituting the value of x,
MK = 6(1.75) + 2
MK = 10.5 + 2
MK = 12.5
Part B
AngleJNK = (5x +2)°
AngleJNM = (3x-6)°
Sum of interior angles of a quadrilateral = 360
Therefore, 2(5x +2)° + 2(3x-6)° = 360
(10x + 4) + (6x - 12) = 360
Collect like terms
10x + 6x - 12 + 4=360
16x = 360 + 8
16x = 368
x = 368/16
x = 23
Substituting the value of x
For angleJNK = 5(23) +2 = 115+2 = 117°
For angleJNM = 3(23) - 6 = 69 - 6 = 63°
32 = 5u +3u solve for u
Answer:
u = 4
Step-by-step explanation:
32 = 5u + 3u = 8u ( divide both sides by 8 )

Step-by-step explanation:
u=4 after you add or combine like terms , you then divide both sides by the same factor
Find the coordinates of the midpoint of EF if E(2, -8) and F(-12, -6).
The coordinates of the midpoint between point E(2, -8) and point F(-12, -6) on segment EF is ( -5, -7 ).
How determine the midpoint between two point?A midpoint is simply a point that divides a line segment into two equal halves.
The midpoint formula is expressed as;
M = ( (x₁+x₂)/2, (y₁+y₂)/2 )
Given the data in the question;
Point E(2, -8)
x₁ = 2y₁ = -8F(-12, -6)
x₂ = -12y₂ = -6Coordinates of midpoint = ?
To determine the midpoint, plug the given points into the midpoint formula above and simplify.
M = ( (x₁+x₂)/2, (y₁+y₂)/2 )
M = ( ( 2 + (-12) )/2, ( (-8) + (-6) )/2 )
M = ( 2 - 12 )/2, ( -8 - 6 )/2 )
M = ( -10 )/2, ( -14 )/2 )
M = ( -5 ), ( -7 )
M = ( -5, -7 )
Therefore, the midpoint of line segment EF is ( -5, -7 ).

Exit. how do I solve this ???
Tate and Nathan will leave $ 19.48 to the server to cover up the bill and the tip when they go out to dinner at Red Robin.
As given in the question,
Since Tate and Nathan both order burgers for $12.49 each,
Total amount payable is
$12.49 + $12.49= $24.98.
Now 18% tip is equal to
18% of $24.98
(18/100) × 24.98
= $4.4964
= $4.50 (rounded to nearest cent).
Total gross amount payable (including 18% tip) is
24.98 + 4.50 = $29.48.
Now subtracting the birthday coupon for $10.00 off,
the net amount payable in the bill is
29.48 - 10.00
= $ 19.48
= 19.48 cents
Therefore, after using the coupon, they will leave the server $19.48 to cover the bill and the tip.

In football, a gain is when a player moves the ball closer to the goal line; whereas, a loss is when the player loses yardage making it difficult to score. Larry plays quarterback for the Eagles. During the team's opening football game, the Eagles have the ball 48 yards away from the goal line. On the first play, the Eagles gain 31 yards on a pass toward the goal line. On the next four plays, the Eagles lose 3, 5, 7, and 4 yards, respectively. What is the distance between the ball and the goal line after these five plays?
A.

The distance that is between the ball and the goal line after these five plays is D. 36 yards.
How to calculate the distance?From the information, the Eagles gain 31 yards on a pass toward the goal line and on the next four plays, the Eagles lose 3, 5, 7, and 4 yards, respectively.
After the first day, the yards remaining will be:

= 17
Now, the total distance between the goal line and the ball will be:
= 17 + 3 + 5 + 7 + 4
= 36

On subtracting "3a – 7b + 12c" from "-5a – 21b + 3c" we get -
- 8a - 14b - 9c
What is subtraction?
Subtraction is an arithmetic operation that represents the operation of removing objects from a collection. Subtraction is signified by the minus sign −.
Given is to subtract "3a – 7b + 12c" from "-5a – 21b + 3c".
Assume that -
A = 3a – 7b + 12c
B = -5a – 21b + 3c
B - A = (-5a – 21b + 3c) - (3a – 7b + 12c)
B - A = -5a - 21b + 3c - 3a + 7b - 12c
B - A = -5a - 3a - 21b + 7b + 3c - 12c
B - A = - 8a - 14b - 9c
Therefore, on subtracting "3a – 7b + 12c" from "-5a – 21b + 3c" we get -

Step-by-step explanation:
First you need to do what is inside the parenthesis
Dividing by a variable with the same base means the powers subtract so if we do this for x we get.
[tex]\frac{x^{\frac{1}{2}}}{x^{-\frac{1}{2}}}=x^{\frac{1}{2}-(-\frac{1}{2})}=x^{1}=x[/tex]
That brings us to
[tex](\frac{3xy^{-\frac{1}{2}}}{y^{-\frac{1}{2}}})^2[/tex]
Then we need to do a similar process for the y variable.
[tex]\frac{y^{-\frac{1}{2}}}{y^{\frac{1}{2}}}=y^{-\frac{1}{2}-(\frac{1}{2})}=y^{-1}=\frac{1}{y}[/tex]

how can you eliminate the fractions from the equation n/5+3/7=2 using just one operation?
Answer:
Multiplying both sides of the equation by 35 eliminates the fractions
Step-by-step explanation:
You want to know how to eliminate the fractions from the equation n/5+3/7=2.
Multiplication property of equalityThe multiplication property of equality allows you to multiply both sides of an equation by the same number without changing the value of the variable. To eliminate fractions, the number we choose can be the least common denominator of the fractions.
ApplicationFractions with denominators 5 and 7 will have a least common denominator of 5·7 = 35. Multiplying the equation by 35 gives ...
35(n/5 +3/7) = 35(2)
7n +15 = 70
Multiplying both sides of the equation by 35 eliminates the fractions.

Since ∠ROP = 125°, ∠POS = 55° is obtained by taking 180° away from 125°. ∠POS and ∠QOR are equivalent terms. Also, ∠ROP = ∠QOS.
What is lines intersecting?
In a plane, intersecting lines are any two or more lines that cross one another. The point of intersection, which can be found on all intersecting lines, is where the crossing lines share a common point.

The intersecting lines (two or more) never cross over at more than one location.
Any angle may be used to intersect the lines in any direction. Always larger than 0° and less than 180°, this angle is generated.

The bar chart is created incorrectly.
There are at least a couple of problems with the chart.
The title suggests it will show numbers of students. Instead it shows the fraction (%) of students in each category.The column labels suggest the first column represents the distribution of skateboarders among students who have bikes. Instead, the column actually shows the distribution of bikers among students who have skateboards. (The labels are reversed.)A correctly drawn chart would be incapable of answering the question in Part B. If it is the intention to answer that question using the chart, a different type of chart is needed: a stacked bar chart showing numbers (or relative frequencies) of students in each category.Part BThe largest number in the table is 80. The fraction that is of the whole is ...
80/(70+30+80+70)
= 80/250 = 8/25 = 0.32
The greatest relative frequency is 0.32. It represents the fraction of students who have both bikes and skateboards.
