How did i get this answer? It is apparent that the girl is capable of running 6 2/3 metres per one second and she must run 100 metres.
First, let's convert 2/3 into a decimal so that it is easier to calculate later. 2/3=0.667 (you can also just do 2 divide by 3 and will end up with the same number)
Now our numbers are 6.667 and 100. Let's divide 100 by 6.667 which estimates to 15
Answer: The correct option is A.
Explanation:
The given equation is,
Multiply both sides by 2.
![2[4(x+5)-5]=\frac{8x+18}{2}](https://tex.z-dn.net/?f=2%5B4%28x%2B5%29-5%5D%3D%5Cfrac%7B8x%2B18%7D%7B2%7D)
Subtract both sides by 8x.
This statement is false for any value of x, therefore the system of equation have no solution and option A is correct.
