Answer: $11
Step-by-step explanation:
To have the same:
11+8=19
19×2=38
The two laws of motion are

Since Mr Sim's speed is 15 km/h less that Mr Low's, we have

Note that the distance d is the same for both equations, because they traveled the same path.
20 minutes is 1/3 of a hour, so at t=1/3 Mr Low traveled the whole distance, while at the same time Mr Sim traveled 4/5 of the distance:

If we multiply Sim's equation by 5/4, we have

Since the left hand sides are equal, we equal the right hand side as well:

Multiply both sides by 12:

Expand the right hand side:

Which implies

U have both a dog and a cat
![\sqrt[3]{8m}^3](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8m%7D%5E3)

- Convert the radical into a fractional exponent using
![\sqrt[n]{x^m} = x^{\frac{m}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5Em%7D%20%3D%20x%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D)

- Use the property that


The simplification would be 8m.
Answer:
Any number over then 1 is greater than -8.67 and any number less than -8.67is greater as well.
