What is the solution to the equation below? ½ x+¾=⅔

lora16 [44]

Answer:

$\boxed{x = - \frac{1}{6}}$

Step-by-step explanation:

$= > \frac{1}{2} x + \frac{3}{4} = \frac{2}{3} \\ \\ = > \frac{1}{2} x = \frac{2}{3} - \frac{3}{4} \\ \\ = > \frac{1}{2} x = ( \frac{2}{3} \times \frac{4}{4} ) - (\frac{3}{4} \times \frac{3}{3} ) \\ \\ = > \frac{1}{2} x = \frac{8}{12} - \frac{9}{12} \\ \\ = > \frac{1}{2} x = \frac{8 - 9}{12} \\ \\ = > \frac{1}{2} x = - \frac{1}{12} \\ \\ = > x = 2 \times ( - \frac{1}{12} ) \\ \\ = > x = - \frac{1}{6}$

X+4,x+12,x-1 and x+5 are in proportion.find the value of x

Anastaziya [24]

Answer:

Step-by-step explanation:

As they are in proportion,

x +4 : x +12 :: x -1 : x + 5

Product of means = Product of extremes

(x + 12)(x -1) = (x +4)(x+5)

Use FOIL method for polynomial multiplication

x*x + x*(-1) + 12*x + 12*(-1) = x*x + x*5 + 4*x + 4*5

x² - x + 12x - 12 = x² + 5x + 4x + 20

Combine like terms

x² + 11x - 12 = x² + 9x + 20

x² + 11x - 12 - x² - 9x - 20 = 0

Combine like terms

x² - x² + 11x -9x -12 -20 = 0

2x - 32 = 0

2x = 32

x = 32/2

x = 16
