Answer:

<h2>z = 6</h2>

Step-by-step explanation:

4(z+1)=2(z-1)+18\qquad\text{use the distributive property}\\\\(4)(z)+(4)(1)=(2)(z)+(2)(-1)+18\\\\4z+4=2z-2+18\qquad\text{subtract 4 and}\ 2z\ \text{from both sides}\\\\4z-2z+4-4=2z-2z-2+18-4\qquad\text{combine like terms}\\\\2z=12\qquad\text{divide both sides by 2}\\\\z=6

Una botella tenía agua hasta de su capacidad. Luego, se agregó litro de agua y la botella quedó llena. Si x representa la capaci
Elena L [17]

Responder:

3 / 4x + 1/2 = x

Explicación paso a paso:

Dado que:

Capacidad total = x

Volumen inicial = cierta fracción * capacidad total

Volumen adicional agregado para llenar = 1/2

Por eso,

Inicial. Volumen + volumen adicional = volumen total

De las opciones:

Un volumen inicial de 3 / 4x

Volumen adicional de 1/2

Volumen total = x

Sumar todo hace que la ecuación:

3 / 4x + 1/2 = x

x - 3 / 4x = 1/2

Por lo tanto, la ecuación correcta de la opción es: 3 / 4x + 1/2 = x

Solve this equation for x. Round your answer to<br> the nearest hundredth.<br> 3 = In(x + 9)
Mrac [35]

Answer:

x ≈ 11.09

Step-by-step explanation:

Using the rule of logarithms

log_{b} x = n ⇒ x = b^{n}

Given

ln(x + 9) = 3 , that is

log_{e} (x + 9) = 3 , then

x + 9 = e³ ( subtract 9 from both sides )

x = e³ - 9 ≈ 11.09 ( to the nearest hundredth )
