Answer:

First choice: 58 seconds.

Step-by-step explanation:

27.8 is approximately 28 seconds, because 8 ≥ 5, so the number rounds up.

30.12 is approximately 30 seconds, since 1 < 5.

So, 28 + 30 is 58. Therefore, 27.8 + 30.12 ≈ 58.

How many solutions are there to the equation below?<br><br> 12x+6=5x
slavikrds [6]

Answer:  There is one solution to the given equation.

Step-by-step explanation:  We are given to find the number of solutions to the following equation :

12x+6=5x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

Since the given equation is linear in one variable x, so it will have only one solution.

The solution of equation (i) is given by

12x+6=5x\\\\\Rightarrow 12x-5x=-6\\\\\Rightarrow 7x=-6\\\\\Rightarrow x=-\dfrac{6}{7}.

Thus, there is one solution to the given equation.
