Answer:

[tex]x = \frac{7}{4} [/tex]

Step-by-step explanation:

[tex]−8(4x−10)=24[/tex]

[tex] \frac{ - 8(4x - 10)}{ - 8} = \frac{24}{ - 8} [/tex]

[tex]4x - 10 = \frac{24}{ - 8} [/tex]

[tex]4x−10=−3[/tex]

[tex]4x=−3+10[/tex]

[tex]4x=7[/tex]

[tex]x = \frac{7}{4} [/tex]

Answer:

[tex]x= \frac{7}{4} [/tex]

Step-by-step explanation:

Let's solve:

[tex]−8(4x−10)=24[/tex]

Step 1: Simplify both sides of the equation.

[tex]−8(4x−10)=24 \\ (−8)(4x)+(−8)(−10)=24(Distribute) \\−32x+80=24[/tex]

Step 2: Subtract 80 from both sides.

[tex]−32x+80−80=24−80 \\ −32x=−56[/tex]

Step 3: Divide both sides by -32.

[tex] \frac{ - 32x}{ - 32} = \frac{ - 56}{ - 32}

\\

x= \frac{7}{4} [/tex]

Answer:

x = -19/2      y = -33/2

Step-by-step explanation:

x - (3x + 12) = 7

x - 3x - 12 = 7

-2x - 12 = 7

-2x = 19

x = -19/2

x - y = 7

-19/2 - y = 7

-y = 33/2

y = -33/2

Answer:

B

Step-by-step explanation:

3 x -9 which is -27. Then you have to add the exponents, so it will be x^4+2 = x^6 , y^3+2 = y^5, z^1+2 = z^3. so your answer will be -27 x^6 y^5 z^3

Answer:

Step-by-step explanation:

Answer:

tom = 166, ben = 581

Step-by-step explanation:

2 + 7 = 9

747 ÷ 9 = 83

therefore 1 part = 83

83 x 2 = 166

83 x 7 = 581

tom has 2 parts so he has 166

ben has 7 parts so he has 581

Answer:

Tom has 166.

Ben has 581.

Step-by-step explanation:

2 + 7 = 9

747 ÷ 9 = 83

83 × 2 = 166

83 × 7 = 581

Answer:

There are 8 nickels and 14 pennies

Step-by-step explanation:

Represent the number of pennies by p and nickels by n.  Then:

p + n = 22, or n = 22 - p

Coin values:

($0.01/penny); ($0.05/nickel).  Therefore, the relation showing the amounts of money involved is:

($0.01/penny)p + ($0.05/nickel)n = $0.54.

But we found earlier that n = 22 - p.  Therefore, the previous equation becomes:

($0.01/penny)p + ($0.05/nickel)(22 - p) = $0.54.

Multiply all three terms by 100 to eliminate the decimal fractions:

1p + 5(22 - p) = 54, or:

1p + 110 - 5p = 54, or:

-4p = -56

Thus, p = 14.  If p = 14, then n = 22 - 14 = 8.

There are 8 nickels and 14 pennies.

Check:  8($0.05) + 14($0.01) = $0.54 (correct)

Answer:

The answer is x=2-(y/2)

Step-by-step explanation:

Answer:

2 - y/2

Step-by-step explanation:

12x + 6y = 24

=> 12x = 24 - 6y

=> x = (24 - 6y)/12

=> x = 24/12 - 6y/12

=> x = 2 - y/2

Answer:

B

Step-by-step explanation:

Since the relationship is linear then the slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (5, - 1) and (x₂, y₂ ) = (10, 1) ← 2 ordered pairs from the table

m = [tex]\frac{1+1}{10-5}[/tex] = [tex]\frac{2}{5}[/tex]

The point (0, - 3 ) indicates c = - 3 , then

y = [tex]\frac{2}{5}[/tex] x - 3 ( multiply through by 5 to clear the fraction )

5y = 2x - 15 ( subtract 2x from both sides )

5y - 2x = - 15 → B

Step-by-step explanation:

since its a power to a power, you multiply so -6 x -3 = 18 so Answer = 5^18

Given:

Diameter of ball = 8 cm

To find:

The volume of the ball.

Solution:

We know that the radius of sphere is half of is diameter.

It is given that the the diameter of ball is 8 cm. So, the radius of the ball is:

[tex]r=\dfrac{8}{2}[/tex]

[tex]r=4[/tex]

The radius of the ball is 4 cm.

The volume of a sphere is:

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

Where r is the radius of the sphere.

Putting [tex]\pi = 3.14, r=4[/tex] in the above formula, we get

[tex]V=\dfrac{4}{3}(3.14)(4)^3[/tex]

[tex]V=\dfrac{4}{3}(3.14)(64)[/tex]

[tex]V=267.946667[/tex]

[tex]V\approx 267.95[/tex]

Therefore, the volume of the ball is about 267.95.

Explanation:

Ignore lines BC and FE. It might help to redraw the figure without those lines present. Refer to the diagram below. Doing this is optional if you can spot what's going on without having to erase those lines.

Notice how angles 1 and 3 are congruent corresponding angles, due to lines FJ and DC being parallel.

Since angle 3 is 55 degrees,  angle 1 is also 55 degrees.

--------------

Once we determine angle 1, we subtract from 180 because angle ABF is supplementary to angle 1 (aka angle ABJ)

In other words,

(angle ABJ) + (angle ABF) = 180

angle ABF = 180 - (angle ABJ)

angle ABF = 180 - (angle 1)

angle ABF = 180 - (55)

angle ABF = 125 degrees

Answer:

3/20

Step-by-step explanation:

Of means multiply. When it says 3/10 of 4/8, it just means 3/10*4/8 which when multiplied across gives you 12/80. Which can be simplified to 3/20.

Step-by-step explanation:

jdiidjeojfomfjfjjdj

are u taking a test Sir??

Answer:

Step-by-step explanation:

a) 5  > 4 +x

4 + x < 5

Subtract 4 from both sides

x < 5 - 4

x < 1

b) 2 ≤ 6c + 14

6c + 14 ≥ 2

Subtract 14 from both sides

6x ≥ 2 - 14

6x ≥ - 12

Divide both sides by 6

x ≥ -12/6

x ≥ -2

c)  -4 > 2b

2b < - 4

Divide both sides by 2

b < -4/2

b < -2

d)

[tex]7 \leq \frac{a}{3}[/tex]

[tex]\frac{a}{3} \geq 7\\\\a \geq 7*3\\\\a \geq 21[/tex]

Answer:

Below.

Step-by-step explanation:

(a). 5 > 4 + x

4 + x < 5      (Note that the sign is flipped)

x < 5 - 4

x < 1.

(b) and (c) are solved in the same way.

(d)  7 <= a/3

a/3 >= 7

Multiply both sides by 3

a >= 21.

(e) - as above.

(f) 6 >= 3(p + 2) - 11

3(p+2) - 11 <= 6

3p + 6 - 11 <= 6

3p - 5 <= 6

3p <= 6 + 5

3p <= 11

p <= 11/3.

Answer:

342,1875

Step-by-step explanation:

Dado

Precio de compra del artículo = 219

Precio de venta cuando el descuento dado es 25% = 219 + 0,25 * 219 = 273,75

Para otorgar un descuento del 25%, este producto debe estar marcado a un precio un 25% más alto que los precios de venta = 273,75 + 0,25 * 273,75 = 342,1875

Queremos saber a que precio debe fijarse un articulo para que cuando le hagamos un descuento del 25%, aun tengamos una ganancia del 25% del costo del articulo.  Veremos que el precio que cumple los requerimentos es $365.

Veamos como resolver el problema:

Sabemos que el costo del articulo es $219. Queremos vender este articulo a precio P.

Cuando vendamos este articulo con un descuento del 25%, queremos obtener una ganancia del 25%, entonces debemos resolver:

P*(1 - 0.25) = $219*(1 + 0.25)

P*0.75 = $219*1.25

P = ($219*1.25)/0.75 = $365

Así, podemos concluir que el precio que debe fijarse para cumplir los requisitos es $365.

Answer:

Step-by-step explanation:

Pythagoras

c² = a² + b²

with c being the Hypotenuse (= the side opposite of the 90 degree angle).

if I understand the question correctly, then the Hypotenuse c is here 7.

=>

7² = (2×sqrt(6))² + b²

49 = (4×6) + b²

49 = 24 + b²

25 = b²

b = 5

Answer:

(7/2, -9/2)

Step-by-step explanation:

to find the midpoint, we can use the midpoint formula, which is:

(x1+x2)/2, (y1+y1)/2

since we know the points (1,-1) and (6,-8) we can plug this into the formula:

for the x-coordinate: (1+6)/2=7/2 (or 3 1/2)

for the y-coordinate: (-1+(-8)/2=-9/2 (or -4 1/2)

so, the midpoint of the line segment would be (7/2, -9/2)

Answer:

Step-by-step explanation:

angle y +60  = 180 degree (being adjacent angles of a trapezium )

angle y =180 - 60

angle y =120 degree

angle x+30 degree = 180 degree (being opposite angles of a trapezium)

angle x =180 - 30

angle x=150 degree

75 + 145 + 90 + y = 360 degree (sum of angles of a quadilateral is 360 degree)

310 + y = 360

y = 360 - 310

y = 50 degree

Answer:

La distancia de C con respecto a A es de 197.788 metros.

Step-by-step explanation:

A manera de imagen adjunta construimos una representación del enunciado del problema, la cual representa a un triángulo cuyos tres ángulos son conocidos y la longitud del segmento AB, medida en metros, son conocidos. Por medio de la Ley del Seno podemos calcular la longitud del segmento AC (distancia de C con respecto a A), medida en metros:

[tex]\frac{AB}{\sin C} = \frac{AC}{\sin B}[/tex] (1)

Si sabemos que [tex]B = 57^{\circ}[/tex], [tex]C = 58^{\circ}[/tex] y [tex]AB = 200\,m[/tex], entonces la longitud del segmento AC es:

[tex]AC = AB\cdot \left(\frac{\sin B}{\sin C} \right)[/tex]

[tex]AC = (200\,m)\cdot \left(\frac{\sin 57^{\circ}}{\sin 58^{\circ}} \right)[/tex]

[tex]AC = 197.788\,m[/tex]

La distancia de C con respecto a A es de 197.788 metros.
