Question

10х+1.5×(2.3-1.7)=13.45

Answer 1

Ответ:

10х+1,5*0,6=13,45

10х+0,9=13,45

10х=13,45-0,9

10х=12,55

х=1,255

Answer 2

To solve the equation 10x + 1.5 * (2.3 - 1.7) = 13.45, follow these steps:

1. First, simplify the expression within the parentheses: 2.3 - 1.7 = 0.6

2. Now, substitute this simplified expression back into the equation: 10x + 1.5 * 0.6 = 13.45

3. Multiply 1.5 by 0.6: 10x + 0.9 = 13.45

4. Next, subtract 0.9 from both sides of the equation to isolate 10x: 10x = 13.45 - 0.9

5. Subtract 0.9 from 13.45: 10x = 12.55

6. Finally, divide both sides by 10 to solve for x: x = 12.55 / 10 x = 1.255

So, the solution to the equation is x = 1.255.
