Charlotte is working two summer jobs, making $21 per hour tutoring and $14 per hour clearing tables. Last week Charlotte worked twice as many hours tutoring as she worked hours clearing tables hours and earned a total of $168. Graphically solve a system of equations in order to determine the number of hours Charlotte worked tutoring last week, x,x, and the number of hours Charlotte worked clearing tables last week, yy.
Answers
Answer: this is the answer please follow to the explanation
Step-by-step explanation:
21x + 14y = 168. X=2y
14y = -21x +168. 2y=x
14 divided by 14 on one side and
-21 + 168 divided by 14 on the other side
You should get...
Y= -3/2x +12

She visited Creepy Cavern at (-2, 5), Bernie's Barn at (-3, 2), Sweet Symphonies at (-3, -1), Rock and Roll Hall at (-2, -4), Whimsical Wonders at (3, -4), Mystery Mansion at (3, 2), and Star Gazing Point at (5, 5). Which of these pairs of places are more than 6 units from one another?
Answers
Answer:
We need to find the distance between the pairs of points to know which is greater than 6units. To do that we make use of this formula:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Where [tex](x_1 , y_1)[/tex] and [tex](x_2 , y_2)[/tex] are two points on the line.
Let us denote Creepy Carven with CC, Bernie Barn as BB, Sweet Symphonies as SS, Rock and Roll Hall as RR, Whimsical Wonders as WW, Mysterial Mansion as MM and Star Grazing point as SG.
The distance between CC (-2, 5) and BB(-3, 2) using that formula will be:
[tex]d = \sqrt{(-3 + 2 )^2 + (2 - 5)^2}[/tex]
Which is [tex]d = \sqrt{(-1 )^2 + (-3)^2}[/tex]
That gives
[tex]d = \sqrt{10} < 6[/tex]
If we do this for BB to SS we have our value greater than 6, SS to RR our value greater than 6, RR to WW greater than 6, WW to MM is equal to 6 and MM to SG is less than 6.
From here we conclude that the pairs of places greater than 6 is:
BB to SS
SS to RR
RR to WW
WW to MM
Answer:
First, plot each of the points and label them.
Determine the distance between the pairs of places listed in each answer choice.
Since Whimsical Wonders and Rock and Roll Hall lie on the same horizontal line, the distance between the two points is the absolute value of the difference of the x-coordinates.
Using this same process, the distance between Bernie's Barn and Mystery Mansion is 6 units, and the distance between Creepy Cavern and Star Gazing Point is 7 units.
Since the Mystery Mansion and Whimsical Wonders lie on the same vertical line, the distance between the two points is the absolute value of the difference of the y-coordinates.
Using this same process, the distance between Rock and Roll Hall and Creepy Cavern is 9 units, and the distance between Sweet Symphonies and Bernie's Barn is 3 units.
Therefore, the pairs of places that are more than 6 units from one another are Creepy Cavern and Star Gazing Point and Rock and Roll Hall and Creepy Cavern.

Which of the following ordered pairs is a possible solution to the equation y = 3x - 2?
Answers
Answer:
D) (1,1)
Step-by-step explanation:
You can find the solution by plugging the x-value of each coordinate into the equation. It will be a solution if the y-value of the equation equals the y-value of the coordinate.
For example:
y = 3x -2
y = 3(1) - 2
y = 3-2
y = 1
1 = 1
(1, 1) are the coordinates that are on the given line.
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given a equation y = 3x -2
To find which coordinates will satisfy the equation:
For coordinates (2, 0)
at x = 2, y should be zero
y = 3 * 2 -2
y = 4
Not satisfied
For coordinates(-3, 0)
at x = -3, y should be 0
y = 3 * -3 - 2
y = -9 -2
y = -11
Not satisfied
For coordinates(0, 2 )
at x = 0, y should be 2
y = 3*0 -2
y = -2
Not satisfied
For coordinates(1, 1)
at x = 1, y should be 1
Y = 3*1 - 2
y = 3 - 2
y = 1
satisfied
Therefore, (1, 1) are the coordinates that are on the given line.

Which expression is equal to (x+2)(x-4)/(x-4)(x+4)
A) x-2/x+4
B) x+4/x+2
C) x-2/x-4
D) x+2/x+4
Answers
Answer:
The expression equal to [tex]\frac{(x+2)(x-4)}{(x-4)(x+4)}[/tex] is [tex]\frac{(x+2)}{(x+4)}[/tex]
Option D is correct.
Step-by-step explanation:
We need to solve the expression [tex]\frac{(x+2)(x-4)}{(x-4)(x+4)}[/tex]
Since it is a fraction, and all terms are multiplying with each other we can cancel out common terms.
Since x-4 is both in numerator and denominator so, it will be cancelled out and we will get:
[tex]\frac{(x+2)(x-4)}{(x-4)(x+4)}\\=\frac{(x+2)}{(x+4)}[/tex]
So, the expression equal to [tex]\frac{(x+2)(x-4)}{(x-4)(x+4)}[/tex] is [tex]\frac{(x+2)}{(x+4)}[/tex]
Option D is correct.

If a shape has four sides, then it is a quadrilateral.
If a shape has four sides, then it is a quadrilateral so option (C) will be correct.
What is quadrilatereal?A quadrilateral is a geometrical 2d shape in which there are four sides and each side is connected and makes a close polygon.
In other meaning, a quadrilateral is a kind of polygon in which four sides for example rectangle, square, and parallelogram are quadrilateral.
a quadrilateral is a four-sided polygon, having four edges and four corners
A parallelogram is a basic quadrilateral with two sets of parallel sides.
The confronting or opposing sides and the opposing angles of a parallelogram are of equal length.
A quadrilateral is a quadrilateral because it has four sides not because it is quadrilateral so it has four sides.
For example, 4 sides are equal so the square is not due to the square all lines will same.
Hence If a shape has four sides, then it is a quadrilateral.

Marco is 6 feet 3 inches tall. There are 2.54 centimeters in 1 inch. What is Marco's height in centimeters?
Answers
Answer:
192 cm
Step-by-step explanation:
Answer:
Step-by-step explanation:
First, let's convert 6 feet 3 inches to just inches. Because there are 12 inches in 1 foot, we can say that there are 72 inches in 6 feet. Combined with the other 3 inches, we can say that Marco is a 75 inches tall.
Now, we can multiply the number of inches we found by 2.54 to get Marco's height in centimeters. This gives us 190.5 cm.
