Answer:
2x+27+x+27=180
3x+54=180
3x=180-54
x=126/3
x=42
angle B=x+27
=42+27
=69 degree
Step-by-step explanation:
Answer:
B=69
Step-by-step explanation:
Supplementary angles have a sum of 180. Set up your formula as
180=(2x+27)+(x+27)
180=2x+27+x+27
180-27-27=3x
126=3x
126/3=x
42=x
Now substitute 42 in place of x for Angle B
Angle B = x+27
B = 42+27
B=69
Check your work by doing the same for Angle A
Angle A = (2x+27)
A=2*42+27
A=84+27
A=111
Now add both together and if you did it right, your answer is 180
69+111 = 180

What is the total length of 15 rods? (enter your answer as a fraction or a mixed number)
Answers
Answer:
4/7
Step-by-step-- It is given that we have cut the 4 ft long.
We have to make it into 7 times it's original piece.
To determine this Is the length of the new rods.
Let the length of each new rod be x.
We need 7 rods-
7x = 4 ft
1 = 4/7x
x = 4x/7x
So, x gets cancelled. Now, we get the answer as . 4/7

Alright, with this, its essentially asking for you to plug in X into each equation for the answer.
With the first box, it asks for y = 5 - x, given the x = -2.
y = 5-x
y=5-(-2)
y=5+2
y=7
With the second box down, it wants things a bit differently, it gives you the y value, and wants for you to find the x. Given this, this question can be done backwards for the x value.
y = 5-x
6 = 5-x
x+6= 5
x=-1
With the third one, its the same thing as with the first box.
y = 5-x
y = 5-0
y = 5
Same thing with the fourth one.
y = 5-1
y = 4

Can someone plz help me on this plz I beg u
Answers
Answer:
8
Step-by-step explanation:
So, lets go over a few things:
First off, all triangles have a total angle of 180 degrees.
Secondly, we know that the first two angles are 57 and 51.
Thirdly, we know that the missing angle is 9x
To solve this, we must add together the known angles, subtract them fro 180, and divide that by 9. This will give us the missing x value.
So, add together the two angles we know:
57+51
=
108
So we know 108 degrees of our triangle. We must find whats left of the 180.
To do this, subtract 108 from 180:
180-108
=
72
So our remaining angle is 72 degrres.
But recall that x isnt the misisng angle, 9x is.
So, to get x on its own, we must divide both the missing angle and 9x by 9:
72=9x
--- ---
9 9
=
8=1x
So now we know that x equals 8.
I hope this helps! :)
Answer:
X = 8
Step-by-step explanation:
Okay so we know that there are a total of 180 degrees in every triangle. We need to create the equation to define the triangle's angles. 51 + 57 + 9x = 180. Then, we will solve for x.
180 = 51 + 57 + 9x we are going to simplify the equation by solving what we can
180 = 108 + 9x * Now we will isolate x
180 - 108 = 9x * Solve the left side of the equation
72 = 9x * Divide both sides by 9
8 = x
Justin likes to get 7 hours of sleep. He woke up after sleeping for 5 1/3 hour. How many more hours does he need to get the amount of sleep he likes?
Answers
Answer:
He needs 1 hour 40 minutes more to get the amount of sleep he likes or 1 2/3 hours
Step-by-step explanation:
Justin likes to get 7 hours of sleep.
He woke up after sleeping for 5 1/3 hour = 5 hours 20 mins
Number of more hours needed to get the amount of sleep he likes= 7 hours - 5 1/3 hours.
1 hour = 60 minutes
1/3 hours = 60/3 = 20 minutes
Hours Minutes
7 00 when we borrow 1 hour we borrow 60 minutes
5 20
1 40
He needs 1 hour 40 minutes more to get the amount of sleep he likes
or 1 2/3 hours

A line passes through points (2,5) and (5, 14). What is the slope of this line?
Answers
We know that:
Slope of a line = change in y coordinate / change in x coordinate
We are given:
First point = (2,5)
Second point = (5, 14)
Calculating the change in y coordinate:
change in y (also represented by Δy) = second y - first y
Δy = 14 - 5
Δy = 9
Calculating the change in x coordinate:
Δx = second x - first x
Δx = 5 - 2
Δx = 3
Slope of the line:
Slope = (Δy) / (Δx)
Slope = 9 / 3 [replacing the values]
Slope = 3

Find the measure of arc CD in p
Answers
9514 1404 393
Answer:
57°
Step-by-step explanation:
TD is a diameter, so arc TCD is 180°. Then arc CD is ...
CD = arc TCD -arc TC
CD = 180° -123°
arc CD = 57°
Find the measure of arc CD in P.
___________________Solution :-Given Information :-Arc TC = 123°Arc TCD = 180° ( Reason :- Arc TCD is the diameter of circle )Arc BT = 90° To Find :-Measure of Arc CD Calculation :-Because Arc TC and Arc CD comprise the Arc TCD,
⇒ Arc TC + Arc CD = Arc TCD
Substituting the values given, We get,
⇒ 123° + Arc CD = 180° ( Reason :- Arc TCD is the diameter of circle )
Now, Transposing 123° to Right Hand Side, We get,
⇒ Arc CD = 180° - 123°
⇒ Arc CD = 57°
∴ Arc CD = 57°
____________________Final Answer :-Arc CD measures 57°

b. the slopes of both functions are positive
Step-by-step explanation:
hope this helps :)
Answer:
C. The slope of function A is positive and the slope of function B is negative.
Step-by-step explanation:
For this problem, you need to determine the slope of each function.
For function A:
You're given y = (1/4)x - 2/3, which is in slope-intercept form y = mx + b. The slope of an equation in slope intercept form is given by m.
So the slope for function A is 1/4.
For function B:
You're given a list of (x, y) points, so use the definition of the slope = [tex]\frac{y2-y1}{x2-x1}[/tex], which gives you the slope from any two (x, y) points on the line. Let's take the first and second points (2, -8) and (4, -9)
Slope = [tex]\frac{-9-(-8)}{4-2} = \frac{-1}{2}[/tex].
Therefore, the slope of function A is positive and the slope of function B is negative.
