Question

3,93t+15+3,9=(8+3,9)−0,07t

Answer 1

3,93t+0,07t=8+3,9-15-3,9
4t = -7
t = -7:4
t = -1,75

Ответ: -1,75

Answer 2

Ответ:

3.93t+0.07t=(8+3.9)-15-3.9

4t=11.9-15.3.9

4t=-7

t=-7/4

t=- семь четвёртых

Answer 3

To solve the equation for 't', follow these steps:

1. Start by simplifying both sides of the equation:

   3.93t + 15 + 3.9 = (8 + 3.9) - 0.07t

2. Perform the operations within parentheses:

   3.93t + 15 + 3.9 = 11.9 - 0.07t

3. Move all terms involving 't' to one side of the equation and constants to the other side. To do this, you can add 0.07t to both sides and subtract 15 from both sides:

   3.93t + 0.07t = 11.9 - 15

4. Combine like terms on both sides of the equation:

   4t = -3.1

5. Now, isolate 't' by dividing both sides by 4:

   t = (-3.1) / 4

6. Calculate the value of 't':

   t = -0.775

So, the solution to the equation is t = -0.775.
