im not sure what you mean can you elaborate
Step-by-step explanation:
You have to get rid of 1/2 by multiplying it by its recriprocal which is like this:
1) 1/2 x 2/1 which equals to zero and you do the same to the other side.
2) -12 x 2/1 = -24x then multiply-24x with 7 which equals -168.
16-x= -24x -168
3) subtract 16 to the other side and subtract 24x with x
23x= -184
4) divide by 23 to isolate x and you get -8
5) x=-8

Therefore, Grayson ran 3 laps.
Answer:
Step-by-step explanation:
We have the equation
with the initial condition
. It is not difficult to notice that this is a linear equation, which has the general expression
.
The solution of this equation is expressed by a general formula:
.
In the particular case of our equation, we have

.
Then, we must calculate the integrals
that implies
,
and

Then,
.
In order to obtain the value of the constant we substitute the initial condition
that implies 
Therefore,
.
