Answer 1

Ответ:

А)14,08-(52,3-х)=1,003

52,3-х=14,08-1,003

52,3-х=13,077

х=52,3-13,077

х=39,223

Answer 2

To solve these equations, let's go through each one step by step:

A) $14.08 - (52.3 - x) = 1.003$

First, distribute the negative sign inside the parentheses:

$14.08 - 52.3 + x = 1.003$

Combine the constants:

$-38.22 + x = 1.003$

Now, isolate $x$:

$x = 1.003 + 38.22$

$x = 39.223$

B) $6.4 \times (x - 2.09) = 6.528$

First, distribute the 6.4:

$6.4x - 6.4 \times 2.09 = 6.528$

Now, simplify:

$6.4x - 13.376 = 6.528$

Add 13.376 to both sides:

$6.4x = 19.904$

Now, isolate $x$:

$x = 19.904 / 6.4$

$x = 3.11$

C) $0.02x + 0.5x + 0.092 = 0.3$

Combine the $x$ terms:

$0.52x + 0.092 = 0.3$

Subtract 0.092 from both sides:

$0.52x = 0.3 - 0.092$

$0.52x = 0.208$

Now, isolate $x$:

$x = 0.208 / 0.52$

$x = 0.4$

D) $1.904 / (3.2x - 28.6) = 0.56$

First, multiply both sides by $(3.2x - 28.6)$ to get rid of the fraction:

$1.904 = 0.56(3.2x - 28.6)$

Expand the right side:

$1.904 = 1.792x - 15.936$

Add 15.936 to both sides:

$1.904 + 15.936 = 1.792x$

$17.84 = 1.792x$

Now, isolate $x$:

$x = 17.84 / 1.792$

$x = 9.95$
