Answer:
4 miles
Step-by-step explanation:
In order to find how many miles the car will travel in 0.5 hours, we can set up a proportion.

We can now cross multiply to find the value of x.

So the car can travel 4 miles in 0.5 hours.
Hope this helped!
Next time add an image, but know that the expression is equal to 657 since..
83 * 8 -7
Use PEMDAS
664 - 7
657
(2x +3)(2x-3)= 0
x= -3/2 x = 3/2
160,000/4 = n
n = 40,000
Answer: n = 40,000
