If -7.6(x - 1) = 7.3 - 7.4x, find the value of -2x.
Marat540 [252]

Answer:

-3

Step-by-step explanation:

Step 1: Write equation

-7.6(x - 1) = 7.3 - 7.4x

Step 2: Solve for <em>x</em>

<u>Distribute -7.6:</u> -7.6x + 7.6 = 7.3 - 7.4x

<u>Add 7.6x on both sides:</u> 7.6 = 7.3 + 0.2x

<u>Subtract 7.3 on both sides:</u> 0.3 = 0.2x

<u>Divide both sides by 0.2:</u> x = 1.5

Step 3: Find <em>-2x</em>

-2(1.5) = -3

professor190 [17]

Answer:

El área del foso es 5.5 m²

Step-by-step explanation:

Hola!

Por favor, mira el esquema adjunto para una descripción del problema.

Viendo la figura, podemos deducir que el área del foso será igual al área del rectángulo formado por el jardín y el foso menos el área del jardín.

Área del foso = área del foso y jardín - área del jardín.

El área de un rectángulo se calcula multiplicando la longitud de la base por la altura:

Área del jardín = 2.5 m · 2 m = 5 m²

Área del rectángulo jardín - foso = 3.5 m · 3 m = 10.5 m²

Área del foso = 10.5 m² - 5 m² = 5.5 m²

El área del foso es 5.5 m²
