Answer:

x = 50

Step-by-step explanation:

5x + 2(3x - 9) = 132 + 8x

5x + 6x - 18 = 132 + 8x

11x - 18 = 132 + 8x

11x - 18 = 8x + 132

11x - 18 + 18 = 8x + 132 + 18

11x = 8x + 150

11x - 8x = 8x - 8x + 150

3x = 150

3x ÷ 3 = 150 ÷ 3

x = 50

What is the equation in point-slope form of the line that passes through (-9, 12) with a slope of 5/6?​
Hitman42 [59]

Answer:

\large\boxed{y-12=\dfrac{5}{6}(x+9)}

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

<em>m</em><em> - slope</em>

<em>(x₁, y₁)</em><em> - point on a line</em>

<em />

We have

m=\dfrac{5}{6},\ (-9,\ 12)\to x_1=-9,\ y_1=12

Substitute:

y-12=\dfrac{5}{6}(x-(-9))\\\\y-12=\dfrac{5}{6}(x+9)

Una estrategia de cálculo mental con
Softa [21]

Esta estrategia se puede aplicar sumando  15,75 + 0,25, –1,8 + –0,20, 3,5 + 12,5 y 2,62 + 7,38 antes de sumar el tercer número dado en cada caso.

<h3>¿En qué consiste está estrategia?</h3>

La estrategia propuesta consiste en sumar dos números decimales que den como resultado un número entero antes de sumar el tercer número decima. Por ejemplo si teneos  1,4 + 0,6  + 1,2, se debe sumar primero 1,4 + 0,6 lo que es igual a 2 antes de sumar el 1,2.

<h3>¿Por qué utilizar esta estrategia?</h3>

Este estrategia es beneficiosa porque facilita sumar números decimales.

<h3>¿Cómo aplicar está estrategia?</h3>
  • 15,75 + 1,2 + 0,25 = 16 (0,25+15,75) + 1,2 = 17,2
  • (–1,8) + 2,45 + (–0,20) = -2 (-1,8-0,20) + 2,45 = 0,45
  • 3,5 + 11,8 + 12,5 = 16 (12,5+3,5) +11,8 = 27.8
  • 7,38 – 1,5 + 2,62 = 10 (7,38+2,62) + 2,62 = 12,62
