Im not sure if you need the work, but the answer is 3.8 hours. you make them into fractions, like in one hour ann could build 1/5 of the model car and sam 1/15 of the car. you use that to then find 1/x (how much they could build together) and multiply by the lcd. Its complicated sorry i cant explain well lol
Answer:
162.5 miles

Answer:
5/1
Step-by-step explanation:
A fraction is the same as division so just do the division and you get 5/1 or just 5
You know that the system of equations has no solution because you get something funky when trying to solve for x like:
![7 = 25](https://tex.z-dn.net/?f=7%20%3D%2025)
This happens because the system dont intersect.
Now there are infinite number of solutions when its the same equation (it may look different because it was multiplied by a scalar).
But in general, you will get something like
![7 = 7](https://tex.z-dn.net/?f=7%20%3D%207)
