4x-2y=14
y=1/2x-1

Answers

Answer 1
Judging by the problem you want me to use substitute method
Since why equals 1/2x-1 you
Do 2(1/2x-1)= x-2
You multiple by 2 cause there’s two on the top for y. So the problem is now 4x-x-2
Combine like terms 3x+2=14
Subtract two on both sides
3x=12
X=4
Go back to the bottom since u know x now do y= 4.1/2-1 solve to get one
Y=1 so your answer is (4,1)

Given square ABCD, what is the length of AD?

Answers

since it's a square, all sides are equal
therefore,
3x - 5 = x + 1
2x = 6
x = 3

sub x into AD, which is 3x-5
= 3(3) - 5
= 9 - 5
= 4

therefore AD is 4 units

Triangle ABC is similar to triangle DEF. The length of AC¯¯¯¯¯ is 12 cm. The length of BC¯¯¯¯¯ is 18 cm. The length of DF¯¯¯¯¯ is 10 cm.



What is the length of EF¯¯¯¯¯?



Enter your answer in the box.

Answers

Answer:If the triangles are similar, the ratio of corresponding sides will be equal.

AC / DF = BC / EF

Substitute their values,

12 / 10 = 18 / EF

EF = 18/12 * 10

EF = 3/2 * 10

EF = 30/2

EF = 15 cm

In short, Your Answer would be 15 cm

Answers

Answer:

Q1: 18 degrees

Q2: 60 sides

Step-by-step explanation:

The sum of the exterior angles is always 360 degrees. With this, do 360/20 to get the amount of sides that are within the shape.

360/20  --> 18 degrees.

Now with the interior angles, it can be found with the equation ((n-2) * 180 degrees) / n = Angle Given. With this, plug 174 degres into your equation.

(n-2) * 180 degrees) / n = Angle Given

(n-2) * 180 degrees) / n = 174

180n -360 / n = 174

180n -360 / 174n

360 = 6n

n = 60

It would be 60 sides.

The answer is 18. 360 divided by 20 will give you 18 hence the 360 is the sum of all exterior angles

Un cubo tiene una superficie de 54 cuadrados. Metros. ¿Cuál es el volumen del cubo en ¿metros cubicos?

Answers

Answer:

27 cubic meters

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Area of cube = 54 square meters

Let, Side = a

Then, Area of cube = 6[tex]a^{2}[/tex]

54 = 6 [tex]a^{2}[/tex]

[tex]a^{2}[/tex] = 9

a = 3

So, we can calculate the volume of cube by using following formula

Volume of cube = [tex]a^{3}[/tex]

By putting the value in the formula, we get

Volume of the cube = [tex]3^{3}[/tex]

= 27 cubic meters

Read the passage from the opinion of the court in Dred Scott v.

Does the Constitution of the United States act upon him whenever he shall be made free under the laws of a State, and raised there to the rank of a citizen, and immediately clothe him with all the privileges of a citizen in every other State, and in its own courts?The court thinks the affirmative of these propositions cannot be maintained. And if it cannot, the plaintiff in error could not be a citizen of the State of Missouri, within the meaning of the Constitution of the United States, and, consequently, was not entitled to sue in its courts.Why is Justice Taneys argument ineffective?He uses the freedom of African Americans as evidence.He uses a previous status of African Americans as evidence.He uses the dissenting argument of the court as evidence.He uses the ruling of the previous court as evidence.5
