Answer:
1336miles.
Step-by-step explanation:
From the question we are told that;
1km represents 0.62miles
1km = 0.62miles
We are to express 2155kilometers in miles.
2155km = x miles
Find x:
Divide both equations;
1/2155 = 0.62/x
Cross multiply;
1 * x = 2155 * 0.62
x = 1,336.1miles
Hence the correct option is 1336miles.
What percent of 12 is 24
Answer:
200%.
100% of 12 is 12 since for example if a coat is 10$ and 100% off then its now 0$. Therefore 200% is twice of 12 making it 24.
24=200% of 12

Answer:
G is equal to (8, -11)
Step-by-step explanation:
We are given the midpoint and one end of the line segment. We can find the other end of it by taking the distance from H to M, doubling it, and adding that to H:
[tex]G(x, y) = H(x, y) + 2(M(x, y) - H(x, y))\\\\G_x = H_x + 2(M_x - H_x)\\G_x = -4 + 2(-6 - (-4))\\G_x = -4 + 2(-2)\\G_x = -4 - 4\\G_x = 8\\\\G_y = H_y + 2(M_y - H_y)\\G_y= 3 + 2(- 3 - 4)\\G_y= 3 - 6 - 8\\G_y = -11[/tex]
So the coordinates of endpoint G are (8, -11)

Answer:
Equation of the line is y = x + 1
Standard Form: x - y = 1
Step-by-step explanation:
Ax + By = C
y = x + 1
-x + y = 1 ("A" must be positive)
x - y = -1
If C = x + 8 and D = 2x + 10, find an expression that equals 2C + 3D in
standard form.

y=12x=25 help please
Answer:
Simplifying
y = 12x + 25
Reorder the terms:
y = 25 + 12x
Solving
y = 25 + 12x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 25 + 12x

Find the value of n that makes DEF-XYZ when
DE = 4, EF = 5, XY = 4(n + 1). YZ = 7n - 1, and
Answer: n=3
Step-by-step explanation:
Understand that you need to set up a proportion before you can try to solve the question through guessing. In this case, YZ would be proportional to XY as EF is proportional to DE. You would write this as: EF/DE=YZ/XY.
Now you want to write an equation. In order to do this remember to multiply by your proportion. Here’s my equation:
5/4(4n+4)=7n-1. Now distribute:
5n+5=7n-1. Now simplify:
6=2n. Now simplify again:
n=3
Hope this helps you with your big ideas math hw!
The value of is n=3
Important information:DEF-XYZ whenDE = 4, EF = 5, XY = 4(n + 1). YZ = 7n - 1.The calculation is as follows:5/4(4n+4)=7n-1.
Now distribute:
5n+5=7n-1.
Now simplify:
6=2n.
n=3

substitution?
A: x, in the top equation
B: y. in the top equation
C: x, in the bottom equation
D: y, in the bottom equation
Answer:
A = Hard to do, B = Easiest, C = Pretty Easy, D = Hard
Step-by-step explanation:
Step 1:
5x - 2y = -18
x - 8y = 80
__________
Step 2:
4(5x - 2y) = (-18)4
20x - 8y = -72
__________
Step 3:
20x - 8y = -72
x - 8y = 80
__________
Step 4:
21x = ?
Also, this equation isnt a substitution question, the way to solve this is by using elimination, you can tell because the values are lined up perfectly, sub. is used when y/x, is on the bottom left or right, and the other is on the opposite.

A triangle has vertices on a coordinate grid at N (7,3), 0(-8, -3), and
P(-8,-8). What is the length, in units, of NO?
Answer:
[tex]d\approx 16.16\ units[/tex]
Step-by-step explanation:
Distance Between two Points in the Plane
Given two points A(x,y) and B(w,z), the distance between them is:
[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]
The triangle formed by the points N (7,3), 0(-8, -3), and P(-8,-8) is shown in the image provided.
We are required to find the distance between N and O:
[tex]d=\sqrt{(-3-3)^2+(-8-7)^2}[/tex]
[tex]d=\sqrt{(-6)^2+(-15)^2}[/tex]
[tex]d=\sqrt{36+225}[/tex]
[tex]d=\sqrt{261}[/tex]
Since 261=9*29:
[tex]d=3\sqrt{29}[/tex]
[tex]\mathbf{d\approx 16.16\ units}[/tex]

What is Meant by Solution of a Linear Equation?The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.
According to the questions,
On Saturday morning, Owen earned $24 raking leaves.
By the end of the afternoon he had earned a total of $62.
The equation to determine whether Owen earned $38 or $31 on Saturday afternoon.
⇒ $62 - $24 = $38
⇒ $24 + $ x = 62

Answer:
to eliminate x: multiply the first by 3, and the second by -4to eliminate y: multiply the first by 2, and the second by 5Step-by-step explanation:
Pick the variable you want to eliminate. Determine the coefficients of that variable in the two equations. Negate one of them. Multiply each equation by the coefficient that came from the other equation.
__
To eliminate x
The x-coefficients are 4 and 3. If we negate 4, then the resulting y-coefficient will be positive. We choose to multiply the first equation by 3, the second by -4.
Here is the result of adding those:
3(4x +5y) -4(3x -2y) = 3(7) -4(-12) ⇒ 23y = 69
To eliminate y
The y-coefficients are 5 and -2. If we negate -2, then the resulting x-coefficient will be positive. We choose to multiply the first equation by 2 and the second by 5.
Here is the result of adding those:
2(4x +5y) +5(3x -2y) = 2(7) +5(-12) ⇒ 23x = -46
Answer:
Step-by-step explanation:
to kill x: duplicate the primary by 3, and the moment by -4 to eliminate y: increase the primary by 2, and the moment by 5 Step-by-step explanation: Pick the variable you need to eliminate. Decide the coefficients of that variable within the two conditions. Refute one of them. Increase each condition by the coefficient that came from the other equation. __ To dispense with x The x-coefficients are 4 and 3. On the off chance that we invalidate 4, then the coming about y-coefficient will be positive. We select to increase the primary condition by 3, the moment by -4. Here is the result of including those: 3(4x +5y) -4(3x -2y) = 3(7) -4(-12) ⇒ 23y = 69 To dispose of y The y-coefficients are 5 and -2. If we nullify -2, at that point the coming about x-coefficient will be positive. We select to duplicate the primary condition by 2 and the moment by 5. Here is the result of including those: 2(4x +5y) +5(3x -2y) = 2(7) +5(-12) ⇒ 23x = -46
