Answer:
480/(x+60) ≤ 7
Step-by-step explanation:
We can use the relations ...
time = distance/speed
distance = speed×time
speed = distance/time
to write the required inequality any of several ways.
Since the problem is posed in terms of time (7 hours) and an increase in speed (x), we can write the time inequality as ...
480/(60+x) ≤ 7
Multiplying this by the denominator gives us a distance inequality:
7(60+x) ≥ 480 . . . . . . at his desired speed, Neil will go no less than 480 miles in 7 hours
Or, we can write an inequality for the increase in speed directly:
480/7 -60 ≤ x . . . . . . x is at least the difference between the speed of 480 miles in 7 hours and the speed of 60 miles per hour
___
Any of the above inequalities will give the desired value of x.

Answer:
Step-by-step explanation:
There is no solution as you have two variables and only one equation. The best you can do is solve for one variable as a function of the other.
Just multiply 4*12 and add 6.
answer =54
The answer is C. 10 units. This is because they have the same y value so they are the same height, and you need to find the distance between -7 and 3. To get from -7 to 0, you add 7, and to get from 0 to 3 you add 3, so 7 + 3 = 10. I hope this helps!
