Answer:
A police chase covering 225 miles at a constant speed of 75 miles/hour will last 3 hours.
Step-by-step explanation:
If the car is traveling at a speed of 75 miles/hour and has traveled a distance of 225 miles, we can solve for the time taken by using the equation
d = r*t
where d is our distance in miles
r is the rate of travel in miles/hour, and
t is the time taken in hours
In this case,
d = 225 miles, and
r = 75 miles/hour
Let's plug these into our equation
225 miles = (75 miles/hour) * t Divide both sides by 75 miles/hour
Our miles units will cancel out, leaving us with
3 hours = t
Therefore, a police chase covering 225 miles at a constant speed of 75 miles/hour will last 3 hours.
To solve this problem you need to know the law of cosines.

Answer:
x = 5
Step-by-step explanation:
We can subtract 3x, add 12, and divide by 4.
7x -12 = 3x +8
4x -12 = 8 . . . . . . . . subtract 3x
4x = 20 . . . . . . . . . . add 12
x = 5 . . . . . . . . . . . . divide by 4
