Question

½•(8-5½x)=2¼-2½!¡!!!!!!!!! Пж

Answer 1

Ответ:$x=1\frac{6}{11}$

Пошаговое объяснение:

$\frac{1}{2} *(8-5\frac{1}{2} x)=2\frac{1}{4} -2\frac{1}{2}$

$4-\frac{11}{4} x=\frac{9}{4} -\frac{10}{4}$

$-\frac{11}{4} x=-\frac{1}{4}-4$

$-\frac{11}{4} x=-\frac{1}{4} -\frac{16}{4}$

$-\frac{11}{4} x=-\frac{17}{4}$

$x=-\frac{17}{4}: (-\frac{11}{4} )$

$x=\frac{17}{11}$

$x=1\frac{6}{11}$

$\frac{1}{2} *(8-5\frac{1}{2} x)=2\frac{1}{4} -2\frac{1}{2}$

$\frac{1}{2} *(8-\frac{11}{2} *\frac{17}{11} )=\frac{9}{4} -\frac{10}{4}$

$\frac{1}{2} *(8-\frac{17}{2} )=-\frac{1}{4}$

$4-\frac{17}{4} =-\frac{1}{4}$

$\frac{16}{4} -\frac{17}{4}=-\frac{1}{4}$

Answer 2

It looks like you've provided an equation with some mixed numbers and symbols. Let's simplify and solve it step by step:

The equation is: ½(8 - 5½x) = 2¼ - 2½!¡!!!!!!!!!

First, simplify the right side of the equation: 2¼ = 2 + ¼ = 2 + 0.25 = 2.25 2½!¡!!!!!!!!! is not a standard mathematical notation. It appears to be an expression with exclamation marks, which typically do not have a mathematical meaning. If you can clarify its meaning, I can help further.

Now, we have the equation as: ½(8 - 5½x) = 2.25

Next, distribute the ½ on the left side of the equation: 4 - 2.5x = 2.25

Subtract 4 from both sides to isolate the term with x: -2.5x = 2.25 - 4 -2.5x = -1.75

Now, divide both sides by -2.5 to solve for x: x = (-1.75) / (-2.5)

x = 0.7

So, the solution to the equation is x = 0.7.
