Answer:

C) x = ½

Step-by-step explanation:

Using the <em>Distributive Property</em> and combining like-terms will give you this:

-12 + 10x = 2x - 8

- 10x -10x

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

-12 = -8x - 8

+ 8 +8

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

-4 = -8x [Divide by -8]

½ = x

Evaluate each expression for the given value(s) of the variables(s).
masya89 [10]

Answer:

9.  \frac{1}{10,000} = 0.0001

10. \frac{1}{81}

Step-by-step explanation:

9. x^{-4}

Evaluate when x = 10.

Substitute x = 10 into the expression

10^{-4}

Apply the negative exponent rule (a^{-n} = \frac{1}{a^n})

Thus:

= \frac{1}{10^4}

= \frac{1}{10^4} = \frac{1}{10,000} = 0.0001

10. 2a^{-1}b^{-3}

Evaluate when a = 6 and b = 3

Substitute

(2*6^{-1})(3^{-3})

Apply the negative exponent rule

(2*\frac{1}{6})(\frac{1}{3^3})

(\frac{2}{6})(\frac{1}{27})

\frac{2*1}{6*27}

\frac{1}{81}

Hallar el menor número no divisible por 4, 6, 9, 11 y 12, tal que al dividirlo por estos números se obtengan restos iguales.
Aloiza [94]

Answer:

397

Step-by-step explanation:

Sea 'p (x)' el número que no es divisible por 4, 6, 9, 11 y 12 de manera que cuando se divide por estos números da un resto igual, tenemos;

Por teorema del resto, tenemos;

p (x) = (x - a) · Q (x) + R

Dónde;

p (x) = El número, que se divide

Q (x) = El cociente

(x - a) = El divisor

R = El resto

Dado que el número más pequeño es 4, el resto, 0 <R <4

Para el número entero más pequeño arriba (x - a) · Q (x), tenemos;

R = 1

Observamos que el mínimo común múltiplo de 4, 6, 9, 11 y 12 = 396, por lo tanto, podemos tener;

(x - a) · Q (x) = 396

R = 1, dar;

p (x) = 396 + 1 = 397

Por lo tanto;

El número que no es divisible por 4, 6, 9, 11 y 12, de manera que cuando se divide por estos números da residuos iguales, p (x) = 397

Find the area of the shape shown below.
valkas [14]

Answer:

<h2><em><u>12 is the total area</u></em></h2>

Step-by-step explanation:

A of triangle = 1/2 * b * h

b = 6

h = 2

2 * 6 * 0.5

= 12 * 0.5

<h2><em><u>= 6</u></em></h2>

A of square = l * w

2 * 2

<h2><em><u>= 4</u></em></h2>

A of Triangle = 1/2 * b * h

2 * 2 * 0.5 =

4 * 0.5

<h2><em><u>= 2</u></em></h2>

2 + 4 + 6

= 6 + 6

<h2><em><u>= 12</u></em></h2>
