Which scenario best matches the inequality x greater than 3 ?

Answer:

Sean dos números A y B.

Sabemos que la suma de estos dos números es igual a 5, entonces:

A + B = 5

Y sabemos que el doble de uno mas el doble del otro da como resultado 15.

entonces:

2*(A + 2*B) = 15

esta es la única forma de interpretar esta ecuación, si en lugar de esta expresión tuviéramos 2*A + 2*B = 15 (pues tambien se puede interpretar como esto), entonces:

tenemos dos ecuaciones:

A + B = 5

2*A + 2*B = 15

Ahora, si sacamos el 2 como factor común en la segunda ecuación tenemos:

2*(A + B) = 15

si dividimos ambas partes por 2:

(A + B) = 15/2 = 7.5

(A + B) = 7.5

Esto se contradice con la primer ecuación:

(A + B) = 5.

Entonces podemos concluir que dichos números no existen.

Dejando esto de lado, nuestras ecuaciones van a ser:

A + B = 5

2*(A + 2*B) = 15

Para resolver esto, el primer paso es aislar una de las variables en una de las ecuaciones, yo voy a aislar A en la primera:

A = 5 - B

Ahora podemos reemplazar esto en la otra ecuación:

2*(5 - B + 2*B) = 15

2*(5 + B) = 15

10 + 2*B = 15

2*B = 15 - 10 = 5

B = 5/2 = 2.5

Y con la primer ecuación:

A + B = 5

reemplazamos el valor de B:

A + 2.5 = 5

A = 5 - 2.5 = 2.5

Ambos números son 2.5.

Answer:

D) 3768 inches

Step-by-step explanation:

Given,

No. of plates = 100

Diameter of each plate = 12inches

So, radius of each plate = 12 / 2 = 6 inches

So, circumference of each plate

[tex] = 2\pi \: r[/tex]

= 2 × 3.14 × 6 inches

= 37.68 inches

Hence, circumference of 100 plates = 100 × 37.68 inches

= 3768 inches

Hence, 3768 inches of gold trim is required (Ans)

Answer:

4

Step-by-step explanation:

Answer:

The orders of magnitude are numbers of the form:

10^n

where n can be any integer number.

So we can write something like:

"A is n orders of magnitude above B

Now we have the quantities:

Amjed cards = 223

Latif cards = 8741

We want to find how many times more trading cards does Latif  have than Amjed.

Then we need to look at the quotient between the number of cards of Latif and Amjed.

8741/223 = 39.2

Now we need to approximate this to the nearest 10^n number.

(..., 0.1, 1, 10, 100, 1000, ...)

The nearest one to 39.2 is 10.

So we can say that Latif's collection is 10.

and 10 = 10^1

then n = 1

Then we can say that Latif's collection is one order of magnitude above Amjed's collection.

Answer:

Step-by-step explanation:

y = (x-3)²-1

This is the equation for an up-opening parabola with vertex (3,-1).

Find the x-intercepts:

0 = (x-3)²-1

(x-3)² = 1

x-3 = ±1

x = 4, 2

The graph crosses the x-axis at (4,0) and (2,0).

Find the y-intercept:

y = (0-3)²-1 = 8

The graph crosses the y-axis at (0,8).

Plot your four points (3,-1), (4,0), (2,0), (0,8). Draw an up-opening parabola through the points.

Step-by-step explanation:

Answer:

he could have the boat for 4 hours with the coupon

t or time is the unknown here to be solved.

The hours Ivan rent the boat multiplied with $8 with $9 discount needs to be less than $31. Hence,

8t - 9 < 31

8t < 31 + 9

8t < 40

t < 5

The hours Ivan can rent the boat has to be less than 5. This is because he wants to spend LESS than 31, 31 sharp is not okay.

Answer:

$217.50

Step-by-step explanation:

I) Make an equation to find the answer:

o = s + 0.25s (original price = sale price + 25% of sale price)

II) Solve:

o = 174 + 0.25(174)

o = 217.50

If the price was 174 after the mark down of 25%, then adding 25% back will give you the answer.

174 + 25% (which is 43.5) = $217.5

Answer:

the length of a room is 2 m longer than its breadth .if the area of its floor is 63 sq.m.calculate the length and the breadth of the room

Length and breadth

Let the length and breadth be l + 2 and l

Now,

[tex] \large \sf \: Area = l + 2 \times l [/tex]

[tex] \large \sf \: 63 = l + 2 \times \: l[/tex]

[tex] \large \sf \: 63 = 2l + {l}^{2} [/tex]

[tex] \large \sf \: {l}^{2} + 2l - 63 = 0[/tex]

[tex] \large \sf \: {l}^{2} (9l - 7l) - 63 = 0[/tex]

[tex] \large \sf \: l(l + 9) - 7(l + 9)[/tex]

Either

[tex] \large \sf \: l = - 9[/tex]

or,

[tex] \large \sf \: l = 7[/tex]

Length can't be negative,

So,

L = 9

B = 7

Answer:

no entiendo me explican que significa por fa

Answer:

here's the right answer- someone on a different website said the same weird thing as the person before me smh

Step-by-step explanation:

If the total weight of the box is 15 lb, then the weight of the apples is 13.5 lb.

Option (2) is correct.

Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics. Simple algebraic equations with merely addition or multiplication to differential equations, exponential equations with exponential expressions, and integral equations are examples of different types of equations. They are employed to represent a number of physics laws.

As per the given data:

The table shows the total weight of the box and the weight of the apples.

From the table:

Total weight of the box - weight of apples = weight of box

7.5 - 6 = 1.5 lb

10 - 8.5 = 1.5 lb

12.5 - 11 = 1.5 lb

If the total weight of the box is 15 lb and the weight of the apples is 13.5 lb

15 - 13.5 = 1.5 lb {weight of box}

Which satisfies the data in the table.

Hence, If the total weight of the box is 15 lb, then the weight of the apples is 13.5 lb.

Find the diagram attached

The Base of the triangle will be equivalent to the the length of the rectangle

Since the base of the triangle is 5units, hence length of the rectangle is 5units

Similarly, the height of the triangle is corresponding to the width of the rectangle

Since the height of the triangle is 2 units, the rectangle will be 2 unts wide. Hence the required answer is 2units

Answer:

x = 49

Step-by-step explanation:

Given

[tex]\frac{x-16}{x+6}[/tex] = [tex]\frac{3}{5}[/tex] ( cross- multiply )

5(x - 16) = 3(x + 6) ← distribute parenthesis on both sides

5x - 80 = 3x + 18 ( subtract 3x from both sides )

2x - 80 = 18 ( add 80 to both sides )

2x = 98 ( divide both sides by 2 )

x = 49

Answer:

x = - 49

Step-by-step explanation:

Solve for X by cross multiplying.
