Answer:
Tthe distance between the police station and the fire station is 4 miles
Step-by-step explanation:
Let's call x the distance between the library and the police station
Let's call z the distance between the police station and the fire station
We know that:
miles
The distance (x) between the library and the police station is 3 miles less than twice the distance (z) between the police station and the fire station
This is:
![x = 2z-3](https://tex.z-dn.net/?f=x%20%3D%202z-3)
We wish to find the distance z.
Then we equate both equations and solve for the variable z
![5 = 2z -3\\\\2z = 5+3\\\\2z = 8\\\\z =\frac{8}{2}\\\\z = 4\ miles](https://tex.z-dn.net/?f=5%20%3D%202z%20-3%5C%5C%5C%5C2z%20%3D%205%2B3%5C%5C%5C%5C2z%20%3D%208%5C%5C%5C%5Cz%20%3D%5Cfrac%7B8%7D%7B2%7D%5C%5C%5C%5Cz%20%3D%204%5C%20miles)
Answer: $350+$85w greater than or equal to $715
Explanation:
$350 = already saved up money
$85w = additional money each week (we don’t know how many weeks we need to save up in order to reach our goal, so the number of weeks is unknown)
The sign is greater than or less than because you either have to reach the exact total of $715 or more than that.
Now, solve.
$350+$85w greater than or equal to $715
$85w greater than or less than $365
w greater than or less than 4
Answer:
It's mostly just definitions so be sure to write down vocab and things like that. My teacher also asked about doing the operations so make sure you are familiar with doing things such as adding and multiplying polynomials. Go over your notes and practice doing examples, it'll help a lot! Good luck! <3
Step-by-step explanation:
The answer is 64 (units). :D
There are no values of x that make the equation true so no solution.
