Answer:
X equals negative 11
Step-by-step explanation:
The angles in a triangle add up to be 180 degrees, and we already have 80 as one angle and 60 as the other. That equals 140 degrees. But now we have x+51. That would equal 191 degrees, so 191-180=11, so x= -11
Answer:
x=-11
What we know=
Angles A'=x+51
Angle B=60
Angle C=80
Angle B' and C'=?
Due to the vertically opposite angle rule, we know angle B' and C' are the same as angle B and C.
So, angle B' is 60 degrees. Angle C' is 80 degrees.
We can add them together to get 140 degrees.
So we have 140, x+51. We can make an equation.
[tex]180=140+51+x[/tex] We can combine like terms (140 and 51) to get 191
A triangle only adds up to 180 degrees. So now you can subtract 180-191=to get x.
Rewrite the following mixed number as a decimal.

A=D+qm, solve for q.........
Step-by-step explanation:
A=D+qm
qm = A - D
q =(A-D) /m
Answer:
q = (A - D)/m
Step-by-step explanation:
A = D + qm
A - D = qm
(A - D)/m = q
So, the solve for q is q = (A - D)/m

what does a dilation preserve?
Answer: Dilations preserve angle measure, betweenness of points and collinearity.
Step-by-step explanation: Dilations preserve angle measure, betweenness of points and collinearity. It does not preserve distance. Simply, dilations always produce similar figures .

-7(w+4) +2w - 15 simplify
Answer:
w=-8.6 is your answer
-5w-43. is the simple version
Step-by-step explanation:
First distrubute the -7 and set equal to 0 so that we can move the w to the other side.
-7w-28+2w-15=0
-5w-43=0
add 43 to both sides so you can slove for w
-5w=43
divide both sides by -5 to isolate the w
w=-8.6

addison and kelsey are running on a path modeled by x^2+y^2-10x-18y-378=0, where the distance is in meters. what is the maximum distance between the runners at any given time
The maximum distance is the diameter of the circle, which is of 44 units.
The equation of a circle of radius r and center [tex](x_0,y_0)[/tex] is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
The diameter is twice the radius, and is the maximum distance between two points inside a circle.In this problem, the circular path is modeled by:
[tex]x^2 + y^2 - 10x - 18y - 378 = 0[/tex]
We complete the squares to place it in the standard format, thus:
[tex]x^2 - 10x + y^2 - 18y = 378[/tex]
[tex](x - 5)^2 + (y - 9)^2 = 378 + 25 + 81[/tex]
[tex](x - 5)^2 + (y - 9)^2 = 484[/tex]
Thus, the radius is:
[tex]r^2 = 484 \rightarrow r = \sqrt{484} = 22[/tex]
Then, the diameter is:
[tex]d = 2r = 2(22) = 44[/tex]
The maximum distance is the diameter of the circle, which is of 44 units.

Alice earns $185 for working 14.8 hours each week. How much money will Alice earn if she increased her hours to 18 1/2 hours per week?
:)
Step-by-step explanation:
185 is to 14.8 as x is to 18.5
185/14.8 = x/18.5
x = 185(18.5)/14.8
x = $231.25

The sum of ages of 3 siblings, Alice, Bruce and Chuck is 27. The sum of ages of Alice and Bruce is 14 and the sum of ages of Bruce and Chuck is 22. Find each sibling's age by using system of linear equations.
Answer:
Alice = 5
Bruce = 9
Chuck = 13
Step-by-step explanation:
alice= x
Bruce = y
Chuck = z
x+y+z= 27
x+y= 14
therefore z= 27-14= 13
Chuck = 13
y+13 (z) = 22
therefore y = 22-13= 9
Bruce = 9
9+13= 22
therefore x= 27 - 22= 5
Alice = 5
confirmation
5 + 9 + 13 = 27
5+9= 14
9 + 13 = 22
Each sibling's age i..e Alice be 5 years, Bruce be 9 years, and Chuck be 3 years.
Given that,
The sum of ages of 3 siblings, Alice, Bruce, and Chuck is 27. The sum of ages of Alice and Bruce is 14 and the sum of ages of Bruce and Chuck is 22.Here we assume Alice be x, Bruce be y, and Chuck be z.Based on the above information, the calculation is as follows:
x + y + z = 27
x + y = 14
So,
z = 27 - 14
= 13
i.e. Chuck = 13
Now
y + 13 (z) = 22
So,
y = 22 - 13
= 9
i.e. Bruce = 9
Now
9+13= 22
So,
x = 27 - 22
= 5
i.e. Alice = 5
Therefore we can conclude that each sibling's age i..e Alice be 5 years, Bruce be 9 years, and Chuck be 3 years.

Flights 204 and 317 are both approaching Hartsfield Atlanta International Airport from directions directly opposite one another and at an altitude of 2.5 miles. The pilot on flight 204 reports an angle of depression of 17 degrees 47 minutes to the tower, and the pilot on flight 317 reports an angle of depression of 12 degrees 39 minutes to the tower. Calculate the distance between the planes.
Answer:
19.26 milesStep-by-step explanation:
Refer to attached picture. Not to scale.
The picture explains all the given parameters.
We need to find the distance d, which is the sum of x and y.
First convert minutes to degrees:
47 min = 47/90 deg = 0.52 deg39 min = 39/90 deg = 0.43 degFind x:
x/2.5 = cot (17.52°) ⇒ x = 2.5*3.1677 ≈ 7.92 miFind y:
y/25 = cot (12.43°) ⇒ y = 2.5*4.5369 ≈ 11.34 miThe distance between the planes:
7.92 + 11.34 = 19.26 miJ=b-q/g solve for b.
Answer:
[tex]j = b - \frac{q}{g} \\ j + \frac{q}{g } = b \\ b = \frac{gj + q}{g} \\ thank \: you[/tex]
