3 days. If every day he runs 10 laps then that would be 4000 meters. 1 kilometer is equal to 1000 meters. That means everyday he runs 4 kilometers. Then after 3 days he would have ran 12 kilometers.
Hello!
-22 = -7 + 3/5 x
Add 7 to both sides
-15 = 3/5 x
Multiply both sides by 5
3x = -75
Divide both sides by 3
x = -25
the answer is -25
Hope this helps!
Answer and Step-by-step explanation:
The computation of points on the ellipse is shown below:-
Distance between any point on the ellipse

To minimize

Now we create a table by applying the critical points which are shown below:
t 
0
<u />
<u />




When t =
, x is
and y is
. So, the required points are 
When t =
, x is
and y is
. So, the required points are 
Multiply the first equation by -7 and the second equation by 8, and then add. Then the correct option is B.
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
The system of the linear equations are given below.
8s – 9t = 15 …1
7s – 2t = 12 …2
Multiply the first equation by -7 and the second equation by 8, and then add.
–56s + 63t = -105
<u> 56s – 16t = 96 </u>
47t = -9
Then the correct option is B.
