In order for us to use any of the angle relationships, what must be true about the two lines that are cut by the transversal?
Answer: If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles formed are supplementary . When two lines are cut by a transversal, the pairs of angles on either side of the transversal and inside the two lines are called the alternate interior angles .

what is 21uv+8b+3u+56bv?
Answer:
(1+7v) (3u+8b)
Step-by-step explanation:
Check the coefficents v is common in 21uv and 56bvb is common in 8b and 56bvu is common in 21u and 3uAdd and subtract the second term to the expression and factor by groupingCheck using FOIL: First,Outer,Inner,LastHope this helps!!
The required solution would be (1+7v)(3u+8b) of the given expression.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
We have been given the expression as:
⇒ 21uv + 8b + 3u + 56bv
There is v common in 21uv and 56bv
There is b common in 8b and 56bv
There is u common in 21u and 3u
We have to Add and subtract the second term to the expression and factor by grouping, we get
⇒ (1+7v)(3u+8b)
Therefore, the required solution would be (1+7v)(3u+8b) of the given expression.

If you are considering speed regardless of direction, the average speed is:
(24 + 16) / 2 = 40 / 2 = 20mph
Although if direction matters, then one number has to be negative since the directions are opposite:
(24 - 16) / 2 = 8 / 2 = 4mph (in the positive direction)

Kim and Anthony start a dog walking business. During their first week, they paid $10 to make their business cards. Kim walked a dog for 15 minutes.
Part A - Which integers represent the dollar amounts either spent or earned during their first week Kim and Anthony were in business? Fill in all that apply.
$5 -$5 $10 -$10 -$6
Answer:
-10$
Step-by-step explanation:
Kim and Anthony spent 10 dollars on business cards and it does not say how much Kim earned for the dog walk so the correct integer is -10$

A NASA spacecraft once landed on the surface of the asteroid named 433 Eros.This asteroid is near Earth and has an average orbital speed of 24.36 kilometers per second. What is its speed in meters per second? 0.02436 meters per second 0.2436 meters per hour 2,460 meters per hour 24,360 meters per second
Answer:
24,360 meters per second
Step-by-step explanation:
The average speed = 24.36 kilometer per second
We were asked to convert this to meters per second
1 kilometre = 1000 metres
Hence
24.36km/s = 24.36 × 1000 meters/seconds
= 24,360 meters/seconds.
The average speed of the asteroid is 24,360 meters/seconds.
Answer:
24,360 meters per second

Recall the scenario about Eric’s weekly wages in the lesson practice section. Eric's boss has been very impressed with his work. He has given him a $2 raise and now Eric earns $12 an hour. His boss also has increased Eric’s work hours to 10 to 25 hours per week. The restrictions remain the same; he needs to work a full-hour in order to get the hourly wage (i.e. working 1.5 hour does not pay him for 1.5 hours but for one hour).
1.) function equation
2.) domain of the function in the set notation
3.) range of the function in the et notation
Answer:
f(x)= 12x where x is the number of hours worked (only whole numbers)
Domain= {10,11,12,13,.............., 25}
Range = { $ 120, $ 132, $ 144,$ 156 ,$ 168, $ 180, $ 192, $ 204, $ 216, $ 228, $ 240, $ 252, $ 264, $ 276, $ 288, $ 300}
Step-by-step explanation:
Let x be the number of hours worked then the function will be
f(x)= 12 (x) for {x=10,11,12,13,.............., 25}
x cannot taken any fractional value or decimal value.
The domain of the function is the input values
Domain= {10,11,12,13,.............., 25}
Now range of the function is the set of all possible output values
f(10)= 12 *10= $ 120
f(11)= 12 *11= $ 132
f(12)= 12 *12= $ 144
f(13)= 12 *13= $ 156
f(14)= 12 *14= $ 168
f(15)= 12 *15= $ 180
f(16)= 12 *16= $ 192
f(17)= 12 *17= $ 204
f(18)= 12 *18= $ 216
f(19)= 12 *19= $ 228
f(20)= 12 *20= $ 240
f(21)= 12 *21= $ 252
f(22)= 12 *22= $ 264
f(23)= 12 *23= $ 276
f(24)= 12 *24= $ 288
f( 25) = 12*25= $ 300
Range = { $ 120, $ 132, $ 144,$ 156 ,$ 168, $ 180, $ 192, $ 204, $ 216, $ 228, $ 240, $ 252, $ 264, $ 276, $ 288, $ 300}

Reflect over the line y = x
Answer:
After the reflection over the line y=x, the image points are:
A'(-1, -2) B'(3, -1) C'(2, -3)Step-by-step explanation:
We know that when a point is reflected cross the line y = x, the x-coordinate, and y-coordinate change places.
i.e.
The reflection of the point (x,y) across the line y = x is the point (y, x).Given
A(-2, -1)B(-1, 3)C(-3, 2)so after the points reflected cross the line y = x
P(x, y) → P'(y, x)
A(-2, -1) → A'(-1, -2)
B(-1, 3) → B'(3, -1)
C(-3, 2) → C'(2, -3)
Therefore, after the reflection over the line y=x, the image points are:
A'(-1, -2) B'(3, -1) C'(2, -3)manoj buys a leather coat costing Rs.900 at Rs 990 after paying the vat . calculate the rate of VAT changed on the coat .
Step-by-step explanation:
Original cost = 900
Cost after VAT = 990
VAT amount = 990 - 900 = 90
Rate of VAT = 90/900×100 = 90/9 = 10%
Given △ACP ≅ △LNX, find each missing measure.
9514 1404 393
Answer:
XL = 13 cm, m∠L = 29°
AC = 21 cm, m∠C = 29°
PC = 13 cm, m∠Y = ?? (there is no angle Y in the figure)
Step-by-step explanation:
The figure on the right shows the triangles are isosceles, with XL = XN. That means also PA = PC. Those side lengths are all the same: 13 cm.
PA = PC = XL = XN = 13 cm
In the same fashion, ...
LN = AC = 21 cm
__
Of course, the angles have a similar relationship:
∠A = ∠C = ∠L = ∠N = 29°
The two base angles in the triangle add to 58°, so the third angle is ...
180° -58° = 122°
∠P =∠X = 122°
_____
Additional comment
As is often the case in over-specified problems, the numbers shown are not consistent The attached figures show the length LN is actually incorrect for the angle and side specified for triangle ACP, or the angles are incorrect for the side lengths specified. What this means is that the answers you get will depend on how you work the problem. Above, we have taken the given numbers and relationships at face value, even though we know they are incorrect.
3b=2p-7 make p the subject
Answer:
p = (3b + 7)/2
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesStep-by-step explanation:
Step 1: Define equation
3b = 2p - 7
Step 2: Solve for p
Add 7 to both sides: 3b + 7 = 2pDivide 2 on both sides: (3b + 7)/2 = pRewrite: p = (3b + 7)/2And we have our final answer!
Step-by-step explanation:
3b = 2p - 7
make p stand alone
3b + 7 = 2p
dividing both sides by 2
p = (3b + 7)/2
A pair of hikers, 18 miles apart, begin at the same time to hike toward each other. If one walks at a rate that is 1 mph faster than the other , and if they meet 2 hours later , how fast is each one walking?
The speed of first hiker is 4 mph and speed of second hiker is 5 mph.
Speed of hiker:Let the speed of first hiker is x mph.
Since If one walks at a rate that is 1 mph faster than the other .
so taht speed of second hiker = (x + 1) mph
It is given that, pair of hikers are 18 miles apart and they meet 2 hours later .So that,
2x + 2(x + 1) = 18
2x + 1 = 9
2x = 9 - 1 = 8
x = 8/2 = 4
Hence, the speed of first hiker is 4 mph and speed of second hiker is 5 mph.

Which statement is true about vertical angles. 1 point Vertical angles are congruent if two lines are parallel. If vertical angles are congruent, then two lines are parallel. Vertical angles are always congruent. Vertical angles are supplementary if two lines are parallel.
Answer:
Vertical angles are always congruent.
Step-by-step explanation:
Vertical angles are formed when two straight lines intersect each other, thereby forming two pairs of opposite angles, which are called vertical angles. Thus, a pair of these vertical angles formed are congruent to each other. So therefore, if two angles are said to be vertical angles, it follows that they are congruent to each other.
Using the diagram attached below, we can see two straight lines intersecting each other to form two pairs of vertical angles:
<a and <b,
<c and <d.
Thus, <a is congruent to <b, and <c is congruent to <d.
Therefore, the standby that is true about vertical angles is that:
Vertical angles are always congruent.
we can describe 3x-2 as an expression.
how can we describe the parts of the expression the arrows point to
Answer:
we can describe the parts of the expression that the arrows
point to 3x-2 such as:
↑(x variable)
[tex]3x-2[/tex] ← (2 constant)
↓
(3 coefficient)
Step-by-step explanation:
Given the expression
[tex]3x-2[/tex]
As we have to describe the parts of the expression the arrowspoint to [tex]3x-2[/tex].
we can describe the parts of the expression that the arrows
point to 3x-2 such as:
