Question

1) 7,05•12,4-x=28,5;. 2)x+25,4=5,04•6,05;

Answer 1

Ответ:

Пошаговое объяснение:

1) 7.05•12.4-x=28.5;

87.42-x=28.5;

-x=28.5-87.42;

-x=-58.92;

x=58.92.

------------

2)x+25,4=5,04•6,05;

x+25,4=30,492;

x=30,492-25.4;

x=5.092.

Answer 2

Let's solve the given equations:

1. $7.05 \cdot 12.4 - x = 28.5$

First, multiply 7.05 by 12.4:

$87.42 - x = 28.5$

Now, isolate x by subtracting 87.42 from both sides:

$-x = 28.5 - 87.42$

Combine the numbers on the right side:

$-x = -58.92$

Finally, multiply both sides by -1 to solve for x:

$x = 58.92$

So, the solution to the first equation is $x = 58.92$.

2. $x + 25.4 = 5.04 \cdot 6.05$

First, multiply 5.04 by 6.05:

$x + 25.4 = 30.42$

Now, isolate x by subtracting 25.4 from both sides:

$x = 30.42 - 25.4$

Combine the numbers on the right side:

$x = 5.02$

So, the solution to the second equation is $x = 5.02$.
