The solution number line is also attached below.
Step-by-step explanation:
C = {x ∈ Z | such that -2 ≤ x < 6 }
It is clear that the x ∈ Z, meaning the x belongs to the set of integers Z.
It is given that -2 ≤ x < 6.
so x must be greater than or equal to -2 and less than 6.
Therefore, the elements of the set C will be:
C = {-2, -1, 0, 1, 2, 3, 4, 5}
In other words,
[tex]-2\le \:x<6\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-2\le \:x<6\:\\ \:\mathrm{Interval\:Notation:}&\:[-2,\:6)\end{bmatrix}[/tex]

Tyler needs to buy a book for school that costs $13 he also wants to get a book for each of his two sisters and he wants to be sure he spends the same amount on each of their books. He only has $27 to spend. Let b represent the amount he can spend on each additional book
Answers
Answer:
[tex]b = \$7[/tex]
Step-by-step explanation:
Given that:
Cost of book that Tyler wants to buy for his school = $13
He wants to buy books for his sisters as well.
Total amount of money present with Tyler = $27
Money to be spent on books for his sisters is same and is represented as [tex]b[/tex].
To find:
The value of [tex]b[/tex].
Solution:
As per question statement, the sum of all the books bought must be equal to $27.
The sum of money spent on all the books = Cost of Tyler's book + Cost of books for his sisters
[tex]\Rightarrow \$13 + b + b = \$27\\\Rightarrow \$13 + 2b = \$27\\\Rightarrow 2b =\$14\\\Rightarrow b =\$7[/tex]
Therefore, Tyler must spend $7 on each of her sister's books.

The statement BI = BK is true from the given information ⇒ B
Step-by-step explanation:
If a line is a perpendicular bisector of a line segment, then
The line intersects the line segment in 4 right anglesThe line intersects the line segment in the mid-point of the line segmentAny point on the line is equidistant from the endpoints of the line segmentLet us find the true statement
∵ Line AB is the perpendicular bisector of segment IK
→ By using the 1st note above
∴ AB ⊥ IK
∴ ∠IJA, ∠KJA, ∠IJB, ∠KJB are right angles
→ By using the 2nd note above
∴ J is the mid-point of IK
∴ IJ = JK
∵ Any point on line AB is equidistant from The endpoints of IK ⇒ 3rd note
∴ AI = AK
∴ BI = BK
∴ The statement BI = BK is true from the given information

A store has a 10% off sale on pants. With this discount, the price of one pair of pants before tax is $17.10 What was the original price of the pants?
Answers
Answer:
$171
Step-by-step explanation:
A store has a 10% off sale on pants. With this discount, the price of one pair of pants before tax is $17.10 What was the original price of the pants?
Let x represent the original price of the pair of pants
From the question, we know that:
10% of x = $17.10
10/100 × x = $17.10
10x/100 = $17.10
Cross Multiply
10x = 100 × $17.10
10x = 1710
x = 1710/10
x = $171
Hence, the original price of the pants = $171

Answer:
Given : PQ = RQ
to find : angle B
PQ = RQAngle B = angle QRP ( angle opposite to equal side are equal). ...(1)angle QRP + 140° = 180° ( linear pair)angle QRP = 180° - 140°angle QRP = 40°from equation (1) Angle B = angle QRP = 40°Answer:
b=40
Step-by-step explanation:
PQ=RQ
That means both sides are the same length which also means they both have the same angel measure of 140.
A super easy way to solve this would be to realize that where p is, the angel is 140.
A straight line is 180.
b and 140 are supplementary angels. [which means they equal 180]
To find b you can make an equation.
b+140=180
or
180-140=b
I'll show you both.
First one you would subtract 140 on both sides to get the variable alone, leaving you with b=40.
For the second one, you just do 180-140 and it also equals 40.
Either way it leaves you with b=40
If you need any more help with angels and whatnot, don't be afraid to reach out. I hope that helps! <3

A submarine is descending to examine the seafloor 2,100 feet below the surface. It took the submarine 8.75 hours to reach the seafloor. What is the submarines rate of descent in feet per hour?
Answers
Answer:
240 feet per hour
Step-by-step explanation:
Given that:
Submarine is descending for examining the sea floor.
Distance of sea floor from the surface = 2100 feet
Time taken for the descend = 8.75 hours
To find:
The rate of descent in feet per hour = ?
Solution:
Here, we are given the distance traveled in feet and the time taken to travel that distance in hours.
And we have to find nothing but the speed of the submarine.
First of all, let us have a look at the relationship among speed, distance and time.
[tex]Speed = \dfrac{Distance}{Time}[/tex]
Putting the values of distance and time.
[tex]Speed = \dfrac{2100}{8.75}\\\Rightarrow Speed = \bold{240\ feet/hr}[/tex]

The solution of the system of equations be:
[tex]x=8,\:y=4[/tex]
Hence, option C is true.
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}4x+7y=60\\ -4x+7y=-4\end{bmatrix}[/tex]
adding both the equations
[tex]-4x+7y=-4[/tex]
[tex]+[/tex]
[tex]\underline{4x+7y=60}[/tex]
[tex]14y=56[/tex]
so the system of equations becomes
[tex]\begin{bmatrix}4x+7y=60\\ 14y=56\end{bmatrix}[/tex]
solve 14y for y
[tex]14y=56[/tex]
Divide both sides by 14
[tex]\frac{14y}{14}=\frac{56}{14}[/tex]
Simplify
[tex]y=4[/tex]
[tex]\mathrm{For\:}4x+7y=60\mathrm{\:plug\:in\:}y=4[/tex]
[tex]4x+7\cdot \:4=60[/tex]
[tex]4x+28=60[/tex]
Subtract 28 from both sides
[tex]4x+28-28=60-28[/tex]
Simplify
[tex]4x=32[/tex]
Divide both sides by 4
[tex]\frac{4x}{4}=\frac{32}{4}[/tex]
[tex]x=8[/tex]
Therefore, the solution of the system of equations be:
[tex]x=8,\:y=4[/tex]
Hence, option C is true.
Beth was working at the grocery store, in the quick check-out line. A customer bought cereal for $3.29 and milk for $3.45. The customer paid with $10.00. How much change does Beth need to give the customer?
Answers
Answer:
Change = $3.26
Step-by-step explanation:
Given the following data;
Cost of cereal = $3.29.
Cost of milk = $3.45.
Amount paid = $10.00
Total cost of items bought = $3.29 + $3.45 = $6.74
Change = Amount paid - Total cost of items purchased.
Substituting into the equation, we have;
Change = $10.00 - $6.74
Change = $3.26
Therefore, Beth need to give the customer a change of $3.26.
