HELP ME FIND X AND Y: 2x = 4y + 6 and 3x - y = -1

Answers

Answer:

x = -1

y = -2

Step-by-step explanation:

To get y by itself:

3x - y = -1

-y = -1 - 3x

y = 1 + 3x

Solve for x with substitution:

2x = 4(1 + 3x) + 6

2x = 4 + 12x + 6

2x = 10 + 12x

-10x = 10

x = -1

Plug the x value into 3x - y = -1

3(-1) - y = -1

-3 - y = -1

-y = 2

y = -2

Answer:

x = -1 and y = -2

Step-by-step explanation:

2x = 4y +6

x = 2y + 3

3(2y+3) - y = -1

6y+9 - y = -1

6y - y = -10

5y = -10

y = -2

2x = 4(-2) + 6

2x = -8 + 6

x = -4 + 3

x = -1

By the Definition of congruent property, we have proved that:

VW ≅ VX

Congruent Property:

The three properties of congruence are the reflexive property of congruence, the symmetric property of congruence and the transitive property of congruence. These properties can be applied to line segments, angles, triangles, or any other shape.

Given: VZ ≅ VY and WY ≅ XZ

Prove: VW ≅ VX

Proof:

(Given): VZ ≅ VY and WY ≅ XZ

By the Definition of Congruent Substitute:

VZ = VY and WY = XZ

⇒ VZ = VX + XZ , and,

VY = VW + WY

By Substituting

VX + XZ = VW + WY

Again,

VX + WY = VW + WY

Now,

By Subtraction property of Equality

VX = VW

VW = VX (Definition of congruent property.)

Complete Question:

IF VZ congruent of VY and WY congruent of XZ. Prove that VW is Congruent of VX.

A football stadium holds 52,000 fans. A college student is doing research and determines that on any given game day, the home team has five times as many fans as the visiting team. In order to help the student in his research, he represents the number of home team tickets as H and the visiting team’s tickets as V.

Answers

If H represents the tome teams tickets and V represents the visiting teams then it would be v+h(5)=52,000.
V= 8,667 tickets
H= 43,333 tickets

The entire exterior of a large wooden cube is painted red, and then the cube is sliced into n^3 smaller cubes (where n > 2). Each of the smaller cubes is identical. In terms of n, how many of these smaller cubes have been painted red on at least one of their faces?A. 6n^2
B. 6n^2 – 12n + 8
C. 6n^2 – 16n + 24
D. 4n^2
E. 24n – 24

Answers

Answer:

B. $6n^2-12 n +8$

Step-by-step explanation:

Given,

The number of smaller cubes = $n^3$

So, the number of cubes that have no coloured faces. = $(n-2)^3$ ,

Note : If a cube painted outside having side n is split into n³ cubes, then the volume volume that is not painted = (n-2)³

Thus, the remaining cubes that have been painted red on at least one of their faces

= Total cubes - cubes with no painted face

$= n^3 -(n-2)^3$

$=n^3 - (n^3 - 8 - 6n^2 +12n)$

$=6n^2-12 n +8$

Hence, OPTION B is correct.

Which statements are true? Check all that apply.A sphere has no faces.
A prism must have a triangular or rectangular base.
A triangular prism has 2 rectangular bases and 4 triangular lateral faces.
A square pyramid must have lateral faces that are squares.
The lateral surface of a cylinder is in the shape of a rectangle when unrolled.

Answers

The true statement about shapes are as follows;

A sphere has no faces.

Facts about three dimensional shapes.

A sphere is rounded three dimensional shape. The volume is represented as follows;

volume = 4 / 3 πr³

where

r = radius

Therefore, a sphere has no faces.

A cylinder is a three dimensional figure . The volume is as follows;

volume = πr²h

where

h = height
r = radius

Hence, the lateral surface of a cylinder is in the shape of a rectangle when unrolled

Apples are on sale for $1.20 a pound. Logan bought 3/4 of a pound. How much money did he spend on apples

Answers

What I did was turn ¾ in to a fraction (which is 75%) then turned it into a decimal (.75)
then I multiplied .75 by 1.20 and .9
So she spent 90 cents on apples
Hope I helped :)

$(3)/(4) * 1.20 = (3.6)/(4) = \huge{\boxed{0.9}}$
