Directions: Given that b ∥ c with d as
transversal. Find the value of x in the
following.
1. ∠4 = 5x, ∠5 = 120°
2. ∠1 = 100°, ∠7 = 10x
3. ∠2 = 3x - 10, ∠6= x + 30
4. ∠4 = 3x + 10, ∠6= 2x + 20
5. ∠1 = 7x + 9, ∠5 = 5x + 31
Plssss I need this now
Step-by-step explanation:
1. Angle 5 = 120 degree
Angle 5 = Angle 6 ( alternate exterior angles are equal )
Therfore, Angle 6 = 120 degree
Angle 6 = Angle 4 ( Vertically opposite angles are equal )
Therfore, Angle 4 = 120 degree
Angle 4 = 5x
120 = 5x
120/5 = x
40 = x
Therefore x = 40 degree.
2. Angle 1 = 100 degree
Angle 1 = Angle 7 ( vertically opposite angles are equal )
Therefore, Angle 7 = 100 degree
Angle 7 = 10x
100 = 10x
100/10 = x
10 = x
Therefore x = 10 degree
I want some more time for this question.
10.507140429 nearest hundredth
Answer:
10.51
Always look to the right of the place you are rounding
so...
if you look at 10.507140429
the 0 after 5 is in the hundredths place
look to the right of 0 and you'll see a 7.
If the number to the right of the place you are supposed to round to is:
5 or greater - round up
less than 5 - round down
Hope this helped

The work of a student to solve a set of equations is shown below:
Equation 1: x + 2y = 10
Equation 2: 2x + 5y = 15
Step 1: −2(x + 2y) = −2(10)
2x + 5y = 15
Step 2: −2x − 4y = −10
2x + 5y = 15
Step 3: 1y = 5
Step 4: x + 2(1) = 10
Step 5: x = 8
In which step did the student first make an error?
Step 1
Step 2
Step 3
Step 4
Answer:
Step 2 has error and step 4 has error.
Step-by-step explanation:
Here we can see that elimination method is applied to solve the system of equations for which -2 is multiplied both sides of equation first
-2(x+2y)=-2(10 which is correct
but in step 2
left side is -2x-4y and the right side is -10 which has to be -20 which makes this step wrong and this is the error made by student.
in Step 4 also ,value of the y has to be 5 but student plugged y =1 which is also error by student.
Correct solution is
-2x-4y= -20
2x+ 5y= 15
on adding ,we get
y = -5
plugging y =5 in equation x+2y= 10 ,we get x+2(-5) =10 ,we get x = 20
therefore (20,-5) is the solution

Answer:
No
Step-by-step explanation:
The graph is not a straight line with define slope, so does not represent a linear function.
__
The graph has segments that are straight lines. It is what we call "piecewise linear."

Step-by-step explanation:
A bag contains eight black cards numbered 1 through 8 and six red cards numbered 1 through 6. You choose a card at random what's the possible outcome
Answer:
14 possible outcomes
Step-by-step explanation:
It is given that :
There are 8 black cards numbered 1 through 8.
Therefore, Black 1, Black 2, Black 3, Black 4, Black 5, Black 6, Black 7, Black 8.
And there are 6 red cards numbered 1 through 6.
Therefore, Red 1, Red 2, Red 3, Red 4, Red 5, Red 6.
So the total number of cards is 8 + 6 = 14 cards.
So, there will be 14 possible outcomes if we choose a card randomly.

Answer:
Third option : 9^10 / 9^2
Step-by-step explanation:
9^2 . 9^6
Formula / Identity : -
a^m . a^n = a^( m + n )
Here,
a = 9
m = 2
n = 6
9^2 . 9^6
= 9^( 2 + 6 )
=9^8
9^10 / 9^2
Formula / Identity : -
a^m / a^n = a^( m - n )
Here,
a = 9
m = 10
n = 2
9^10 / 9^2
= 9^( 10 - 2 )
= 9^8
Therefore,
9^10 / 9^2 is equivalent to 9^2 . 9^6.
The sum of two circles is 80 pi square meters. Find the length of the radius if one of them is twice as long as the other
Answer:
Length of Radius of large circle= 8
Lenght radius of first circle= 2
Step-by-step explanation:
THIS IS THE COMPLETE QUESTION
The sum of the areas of two circles is 80π square meters. Find the length of a radius of each circle if one of them is twice as long as the other.
What is the radius of the larger circle?
Area of a circle can be calculated by Below formula
A = πr^2............eqn(1)
Let ( X) = area of first circle
Y= the area of second circle
Rx= radius of first circle
Ry = radius of second circle
From the question, we know that
[X+ Y] = 80π .......eqn(2)
Substitute the radius formula for the area,
[π(Rx)^2 + π (Ry)^2] = 80π ......eqn(3)
But from the question, Radius of second circle is twice of the second one, then
Ry = 2Rx ..........eqn(4)
If we substitute eqn (4) into eqn(3)
[ π(Rx)^2 + π (2Rx)^2 = 80π
If factorize π out, then cancel it out
π[(Rx)^2 + π (2Rx)^2 = 80π
Then we have
(Rx)^2 + 4(Rx)^2 = 80
5(Rx)^2 = 80
(Rx)^2= 80/5
(Rx)^2= 16
(Rx)= 4
From eqn(4)
Ry = 2Rx
Ry= 2(4)
Ry= 8
Rx= 2 and Ry= 8
Hence, radius of first circle= 2
Lenght Radius of second circle= 8

Given the definitions of f (x) and g(2) below, find the value of g(f(5)).
f(x) = x² - 6x – 6
g(x) = -3x + 11
Answer:
[tex]g(f(5)) = 44[/tex]
Step-by-step explanation:
First, solve for [tex]f(5)[/tex]
[tex]f(5) = 5^2-6(5)-6 = -11\\[/tex]
Then, plug in what you got for [tex]f(5)[/tex] into [tex]g(x)[/tex]. Since [tex]f(5) = -11[/tex] you will be solving for [tex]g(-11)[/tex].
[tex]g(-11) = -3(-11) + 11 = 44[/tex]
the answer is 44.

Answer: 55 Square inches
Step-by-step explanation:
You should find the area of the square and rectangle separately
To find the area you multiply length times width, so the area of the square is 4×4 which equals 16
Then you do the same to the rectangle, 13×3=39
To find the area of the whole figure you add the area of the two shapes together 16+39 which should give you 55

Solve for x. Round your answer to the nearest tenth. HELPPPPP!
Answer:
x = 32.6°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin x = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{7}{13}[/tex] , then
x = [tex]sin^{-1}[/tex] ([tex]\frac{7}{13}[/tex] ) ≈ 32.6° ( to the nearest tenth )
Find the value of x that makes the following equation true
- 4x + 26 = -2
Answer:
first collect the like terms so that you have -4x is equals to -2 - 26 then negative 4x is equals to -28 divided by -4x is equals to 7

Grayson ran 2 1/2 miles around the track .each lap is 5/6 of a mile .how many laps did Grayson run?
Given:
Number of miles covered = [tex]2\dfrac{1}{2}[/tex]
Length of each lap = [tex]\dfrac{5}{6}[/tex] of a mile.
To find:
The number of laps.
Solution:
We know that,
[tex]\text{Number of laps}=\dfrac{\text{Number of miles covered}}{\text{Length of each lap}}[/tex]
[tex]\text{Number of laps}=\dfrac{2\dfrac{1}{2}}{\dfrac{5}{6}}[/tex]
[tex]\text{Number of laps}=\dfrac{\dfrac{5}{2}}{\dfrac{5}{6}}[/tex]
[tex]\text{Number of laps}=\dfrac{5}{2}\times \dfrac{6}{5}[/tex]
[tex]\text{Number of laps}=3[/tex]
Therefore, Grayson ran 3 laps.

Answer:
XZ = 42
Step-by-step explanation:
By the property of similar triangles,
"If two triangles are similar, their corresponding sides will be proportional."
By applying the property of similarity in ΔABC and ΔXYZ,
[tex]\frac{AB}{XY}= \frac{BC}{YZ}= \frac{AC}{XZ}[/tex]
[tex]\frac{4}{24}=\frac{8}{48}= \frac{7}{XZ}[/tex]
[tex]\frac{1}{6}= \frac{7}{XZ}[/tex]
XZ = 42
Therefore, length of unknown side XZ = 42 units.
