Question

1) 2,17 + х = 3,42; 2) 9,1 : х = 2,6

Answer 1

Пошаговое объяснение:

1) 2,17 + х = 3,42

x + 2,17 = 3,42

x + 2,17 - 2,17 = 3,42 - 2,17

x = 1,25

2) 9,1/x = 2,6

9,1 = 2,6x

9,1/2,6 = 2,6x/2,6

их нужно упростить

x = 3,5

Answer 2

Ответ:

1.1,25

2.3,5

Пошаговое объяснение:

3,42-2,17=1,25

9,1:2,6=3,5

Answer 3

To solve the given equations for $x$, we'll follow these steps:

1. Equation 1: $2.17 + x = 3.42$

   Subtract $2.17$ from both sides to isolate $x$:

   $x = 3.42 - 2.17$

2. Equation 2: $9.1 \div x = 2.6$

   To isolate $x$, we'll divide both sides by $2.6$:

   $x = \frac{9.1}{2.6}$

Now, let's calculate the values of $x$ for each equation.

1. For the first equation: $x_1 = 3.42 - 2.17 = 1.25$

2. For the second equation: $x_2 = \frac{9.1}{2.6} \approx 3.5$

So, the values of $x$ for the given equations are: $x_1 \approx 1.25$ $x_2 \approx 3.5$
